Bio 499CB (Loomis Cancer) kdorfman Thu, 09/08/2022 - 20:59

Kari Loomis honors thesis seminar

Librarian does workshop on library research.

We do Bradford assay lab:

Explain Bradford assay.

Add some Bradford reagent to some BSA - Ask how much protein?

Need standards to compare to!

  • Bradford concentrate from Bio-Rad 500-0006
  • dilute 1:4 with water
  • Make BSA solution 0.1 mg/mL (dilute from the test 2 m/mL test solution
  • Students share a plate:
    • one uses top row
    • one uses bottom row
  • write a program on PS2

Student protocol:

  • Make a 2-fold dilution series of the BSA
    • 0.5 mL water in each tube (except the first)
    • 1 mL BSA into first tube
    • .5 mL to next tube, mix, transfer to next, etc.
  • Put 160 uL BSA into each well
  • put 160 uL water in one well. (Why?)
  • Add 40 uL Bradford
  • Read plate

Data management

  • Stupid Excel Tricks
  • Art of the standard curve
  • Make your own std curve.
  • How would you estimate the concentration of protein in a solution that had an Abs of:
    • 0.5
    • 0.4
    • 3

Computers, servers, etc. kdorfman Wed, 08/19/2009 - 16:55

The OIT wireless network is installed throughout the ISB. Make sure you have turned on AirPort or your wireless receiver, and sign in using your OIT account username and password.

Set up your bcrc account here: https://wahoo.nsm.umass.edu/passwd/

Computers that are plugged into the network in the biology labs are on the BCRC server; sign in as yourself (after you have set up your account).

Getting to Wahoo files from home

Getting to Wahoo files from home kdorfman Sat, 10/29/2011 - 17:15
  • Get and install Filezilla (see here).
  • Open FileZilla
  • Open Site Manager from the File Menu:
    • Host name: wahoo.nsm.umass.edu
    • Username: your bcrc username
    • password: your bcrc password
    • port: 22
    • Protocol: SFTP
    • Logon Type: ask for passwork
    • User: your BCRC username
  • Click Connect
  • Enter your BCRC username and password
  • The first time, you get a warning about an unknown host. Check the box next to Always trust this host, add this key to the cache, and click OK
  • You should be in a directory called something like /u1/home/bio/username (with your bcrc username, of course).

  • Clear the Remote site and type the appropriate one of these:

    • /export/quantbiol
    • /export/Bioimaging
    • /export/mboms

  • Enlarge the absurdly small window under the remote site bar and scroll to find your microscope folder. Move files between local and remote folders by drag-and-drop, or by right click and upload (local to remote) or download (remote to local)

Voilà!

Screen Capture

Screen Capture rootlet Fri, 04/02/2010 - 14:46

You can capture still images of videos of anything on the computer screens that Biology supports.

Capture Stills

To capture still images, you can use some magic keystrokes:

Capture whole screen: Command + Shift + 3

Capture region: Command + Shift + 4 to turn cursor to cross-hairs, then select region.

There is also an application in the Utilities folder called "Grab" that will let you set some options or get images just of particular windows.

Capture Video

To capture video, you need to use the command-line. Videos of the entire screen are very large. You might want to use the System Preferences to set the screen resolution lower before starting to capture video. We're using the vnc2flv project. Start up Terminal (Also in the Utilities folder, but there a shortcut in the Dock). You can use two commands to start recording video. With any luck, it will be as simple as this:

First, go to the Desktop to save your work there: delfeno:~ sbrewer$ cd Desktop

Then start x11vnc: delfeno:Desktop sbrewer$ x11vnc &

You'll see a bunch of output -- once the output stops, hit return to get the prompt back, then type: delfeno:Desktop sbrewer$ flvrec.py

It will record video and save it in a file on the Desktop until you tell it to stop. You tell it to stop by typing Control + C. You should end up with a file on the Desktop called something like "out201004020900.flv". You can open this file using VLC to watch the video. To import the file into iMovie, you need to transcode the file into something iMovie understands: delfeno:Desktop sbrewer$ ffmpeg -i out201004020900.flv -sameq out201004020900.mov

The .mov file can be imported into iMovie, where you can edit the clip, add a sound-track, or combine with other videos.

Below is a complete session so you can see all the parts put together.

Projectors

Projectors kdorfman Wed, 06/17/2009 - 14:50

There are two different kinds of projectors in the ISB biology/biochemistry lab wing:

Rooms 360 and 364 have the higher quality projectors.

In 360, the projector is turned on via the Crestron. Hold down the video button until the projector turns on, then press the pc button to switch to your computer.

The instructor's computer, at the central microscope, has a mini-DVI to DVI adaptor connection to the cable running up the central pole.

For best resolution from the instructor's computer, log in as bcrc, then go to system preferences>displays, and pick 1344 x 1008 on the projector. Switch to the monitor, and go to arrangement, set it to mirror images. Set the resolution to 1344 x 840.

Use the remote control (in the drawer at the window side of the room labeled "remote control") to turn the projector on and off if the Crestron doesn't seem to work.

To connect to the projector via VGA, use the connector on the Crestron.

To turn the projector off, press the video button until the light blinks.

In 364, there are two connections to the projector: under the window to the right of the screen (#2), and at the desk behind the projector (#1). Connecting to the jack at the window overrides the signal from the jack at the desk. The front jack should also give you a better image.

In room 264, there are two projector jacks: under the window to the right of the screen (#2), and at the desk behind the projector (#1). The jack at the front gives you better video quality, but if you need sound, you need to use the jack by the desk.

To reset the projector if is claiming input from video instead of computer, use the remote (in a labeled drawer near the jack at the front of the room). Or unplug the projector (the white cable from the projector to the ceiling outlet), wait a minute, then replug it.

Link to Programs here

sign in to the "student" account
user = .\student pw = student@ISB364

Find Optima Control in the start menu

Folders icon pinned to taskbar

Data files go to: This PC > Local Disc (C:) > users > student > documents
(also to backups)

Find protocols to import in: This PC > Local Disc (C:) > users > Public > Public Downloads > PS1_Protocols

Plate IDs (in the run menu)
ID1 is file name. Be sure to give a file name

To get the meta data on the output csv file:
Setup
Program configuration
preferences
define format

Set Preferences before running a script! See p 28 of user manual ii, below.

Setup > Program Configuration > Define Format > Filename and Path

File info

Overwrite, append, make new file with same name + number

Header:

  • no header - just the data - useful for files that have to be compiled
  • long header includes wavelength - just the right amount of info (USE THIS)
  • full header (Ex, Em wavelength, date, time, etc) way too much info
  • short header does not include wavelength
  • Danish headers writes the file name next to the row ID. (!?!)

Style

  • Table: no well numbers, or wavelength indicators, etc. Just the results in plate layout form.
  • Table with well numbers: puts the well IDs next to the reading (Very hard to read)
  • Table with well numbers (only measured wells)

  • Table with well numbers in plate layout style: USE THIS

  • List (Literally, a list. no plate info. all values in one column)

  • List with well numbers

    A B
    1 A01 10
    2 A02 12
    3 A03 11
    4 A04 13

  • List with well numbers (only measured wells): puts a - for a skipped well)

  • List sorted by wells (all cycles in one row, chromatics in separate blocks)
  • List sorted by wells with well numbers
  • List sorted by well numbers (only measured wells)
  • List sorted by wells (all cycles/intervals/channels/chromatics in one row)
  • List sorted by wells 2 " " " (only measured wells)

Script mode

For i = 1 to 72 This is the counter
id 1 = "BOD1" BOD1 is the file name
id 1 = "BOD1" i makes a separate file for each run, called BOD1_1. BOD1_2 etc.

Labels

Labels kdorfman Wed, 06/17/2009 - 14:15

These are files for making perforated cardstock labels for the frames in the drawers and cupboards, tough tags for 1.5 mL and 0.5 mL microfuge tubes, and tough spots for 1.5 mL microfuge tubes.

You may save any of these files to the desktop and alter it there, or alter it and print it, but you may not save changes to the original.

The labels already written are for illustrative purposes - clear them or rewrite them as you see fit.

0.5 mL microtube labels kdorfman Wed, 06/17/2009 - 14:35

Use this template to make labels for half-mL microfuge labels on Tough-Tags TTSW-2240 from Diversified Biotech (can be ordered from USA Scientific or Krackeler)

The printing tends to drift as the printer moves down the page, so stay away from the margins of the labels.

You can send a page through the printer more than once, but be sure to follow the diagram on the paper feed that shows you which way the paper faces!

Sterilization

Sterilization kdorfman Tue, 06/16/2009 - 17:50

Sterilize anything that cells might grow in.

Autoclave glassware, tips, and microfuge tubes.

Autoclave most media and salt solutions.

Do not sterilize by autoclave items containing:

  • detergents (e.g., SDS) - they can boil over

  • heat sensitive ingredients (e.g., vitamins, hormones, antibiotics, proteins)

  • sugar in growth medium (the sugars and amino acids may react together, reducing the concentration of both)

  • HEPES

  • DTT (dithiothreitol)

  • Beta mercaptoethanol

  • corrosives (e.g. acids, bases, phenol)

  • solvents or volatiles (e.g. ethanol, methanol, chloroform, acetone, formaldehyde, formalin or glutaraldehyde)

  • chlorine (e.g., bleach)

  • anything radioactive

Filter sterilize any liquid that must be sterile, and that you cannot autoclave.

If the green light is on, press the red reset button.

  • Biohazard Waste: See here: https://wahoo.nsm.umass.edu/content/biohazard-waste

  • Tips: Load racks into boxes wearing gloves (this caution is primarily for RNA work, as most people's skin has RNase on it).
    15 minute sterilization; 40 min drying time; open autoclave CAUTION - HOT! to let steam escape.
    If there is too much condensation inside the boxes, put them in the oven at ~60C for ~an hour.

  • Microtubes: Put into 600 mL plastic jars, screw cover on loosely, so the steam will penetrate. Same time as for tips.

  • Liquids: Larger volumes require longer sterilizing times. Use this table:

Drierite Regeneration

Drierite Regeneration margaret Thu, 10/06/2011 - 18:34

For crystals: 1 hour at 210° C (=425° F) in shallow glass pan. See details below:

For cartridge: 3 hours at 150° C (=~300° F), perforated top down. Blue means full reactivation.

REGENERATION OF DRIERITE DESICCANTS After normal use, any of the forms of DRIERITE may be regenerated for reuse. The operation is simple and involves only standard equipment. The used and exhausted desiccant should be ventilated to remove vapors, if any, and stored in a convenient container until a sufficient amount is accumulated to justify the work of regeneration.

Regular and Indicating DRIERITE For the regeneration of Indicating DRIERITE and small lots of Regular DRIERITE , the granules may be spread in layers one granule deep and heated for 1 hour at 210° C or 425° F. The regenerated material should be placed in the the original glass or metal container and sealed while hot. The color of the Indicating DRIERITE may become less distinct on successive regenerations due to the migration of the indicator into the interior of the granule and sublimation of the indicator.

The Importance of Temperature The temperature at which DRIERITE desiccants are regenerated is crucial in restoring DRIERITE to its original condition. Absorbed moisture is water of hydration and is chemically bound to the calcium sulfate of DRIERITE. Temperatures in the range of 400° - 450° F are required to break these bonds and release absorbed moisture. Lower temperatures, regardless of heating time, will not regenerate DRIERITE unless applied under vacuum (28" Hg, 325° F or 26" Hg, 275° F). Care should be taken not to overheat DRIERITE Desiccants. High temperatures can alter the crystal structure and render the desiccants permanently inactive.

  • Spin 0.5 - 5 mL bacterial culture in 1.5 mL tube 20 sec full speed

  • Add 200 uL P1 (red), resuspend pellet

  • Add 200 uL P2 (green); mix by inverting 2-4 times. Clear, viscous, purple solution indicates cell lysis

  • Add 350 uL P3 (yellow). Mix thoroughly. DO NOT VORTEX. Turns yellow when neutralization is complete.

  • Incubate RT 1-2 min

  • Spin 2 min

  • Put column into collection tube, transfer supernatant. DO NOT DISTURB GREEN PELLET (I found it wasn't green, but OK)

  • Spin 30 sec

  • Discard flow through, put column back into emptied collection tube

  • Add 200 uL Endo-Wash Buffer to the column, spin 30 sec

  • Add 400 uL Plasmid wash buffer to the column, centrifuge 1 min

  • Transfer column to clean 1.5 mL microcentrifuge tube

  • Add 30 uL DNA Elution Buffer

  • Spin 30 seconds. Plasmid DNA is in the collection tube

Peroxide testing

Peroxide testing kdorfman Tue, 10/09/2018 - 20:46

Preparation

  • Samples containing more than 25 mg/L H2O2 (Cat. Nos. 110011) or 100 mg/Ll H2O2 (Cat. No.110081) must be diluted with distilled water or peroxide-free ether.

  • The pH of the aqueous sample must be within the range 2-12 If necessary, buffer the sample wit sodium acetate or, respectively, adjust the pH with hydrochloric acid

Test Procedure

  • For aqueous solutions:

    • Immerse the reaction zone of the test strip in the pretreated sample (15 – 30 C) for 1 sec.
    • Allow excess liquid to run off via the long edge of the strip onto an absorbent paper towel and after 15 sec (Cat. No. 110011) or after 5 sec (Cat. No. 110081) determine with which color field on the label the color of the reaction zone coincides most exactly.
    • Read off the corresponding result in mg/L H2O2

  • For organic solvents:

    • Immerse the reaction zone of the test strip in the pretreated sample (15 – 30 oC) for 1 sec.

    • After the solvent has evaporated (gently fan the strip back and forth for 3 – 30 sec), immerse the reaction zone in distilled water for 1 sec and allow excess liquid to run off via the long edge of the strip onto an absorbent paper towel.

    • After 15 sec (Cat. No. 110011) or after 5 sec (Cat. No. 110081) determine with which color field on the label the color of the reaction zone coincides most exactly.

    • Read off the corresponding result in mg/L H2O2

General Notes

  • any blue within 3 minutes is a positive result

  • If the color of the reaction zone is equal to or more intense than the darkest color on the scale or in another color emerges, repeat the measurement using fresh samples diluted with distilled water or, respectively, peroxide-free ether until a value of less than 25 mg/L/ H2O2 (Cat. No. 110011) or 100 mg/L (H2O2) (Cat. No. 110081) is obtained.

In the case of Cat. No. 110081 the reaction zone indicates values within the measuring range also for H2O2 contents from 5000 mg/L (0.5 %) up.

Biohazard Waste kdorfman Tue, 10/11/2011 - 16:50

Check the red biohazard trashcans, usually found in 360, 364, or 368.

If it is more than half full, or if it really stinks, autoclave it.

Wear gloves! Put the clear bag into a Nalgene autoclave basket, but don't seal it up tight. (If you do, it will explode in the autoclave.) Double bag it if it has a lot of liquid in it.

Set it for 60 minutes sterilization, liquid cycle.

When it is done, make sure the "autoclaved" sign on the bag has turned dark, then seal the bag and put a non-hazardous waste sticker on it, put it inside a black trashbag, and throw in the regular trash.

Santa Cruz Biotechnology sc-208

From Wikipedia: Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways. PKC family members also serve as major receptors for phorbol esters, a class of tumor promoters. Each member of the PKC family has a specific expression profile and is believed to play a distinct role in cells. The protein encoded by this gene is one of the PKC family members. This kinase has been reported to play roles in many different cellular processes, such as cell adhesion, cell transformation, cell cycle checkpoint, and cell volume control. Knockout studies in mice suggest that this kinase may be a fundamental regulator of cardiac contractility and Ca2+ handling in myocytes.[5]

Protein kinase C-alpha (PKC-α) is a specific member of the protein kinase family. These enzymes are characterized by their ability to add a phosphate group to other proteins, thus changing their function. PKC-α has been widely studied in the tissues of many organisms including drosophila, xenopus, cow, dog, chicken, human, monkey, mouse, pig, and rabbit. Many studies are currently being conducted investigating the structure, function, and regulation of this enzyme. The most recent investigations concerning this enzyme include its general regulation, hepatic function, and cardiac function.

From Drew Sigma T6557-100UL

  • Working concentration is 1:5000
  • Frozen stock is diluted 1:1 with glycerol
  • 5 uL aliquots (in half-mL tubes) should be diluted:
    • 1:50 in the tube: add 245 uL PBS-Tw-BSA to make 1:100 stock
    • 1:50 for use (1 uL 1:100 antibody + 49 uL PBS-Tw-Az-BSA per coverslip)

Drew's Protocol:

  • Rinse in PBS
  • Fix in paraformaldehyde 15 minutes
  • Rinse with PBS-Triton
  • Rinse with PBS-Tween
  • Rinse with PBS-BSA 1 hour
  • Dilute Ab 1:5000 in BSA
  • Incubate with Ab 2hr RT
  • Rinse with PBS 3x
  • Incubate with secondary Ab (in BSA)
  • Rinse with PBS 3x
  • Mount

Test Protocol:

  • coverslips already fixed in paraglut, stored in PBS-Tw-Az 1
  • 1 uL Ab (as supplied by Sigma) into 99 uL PBS-BSA (save!)
  • 1 uL 1:100 Ab into 499 uL PBS-BSA (save for the rest of the slides if it works!)
  • 50 uL onto coverslip - 2 hr RT incubation
  • rinse with PBS-Tw-Az
  • 50 uL Goat anti mouse 488

  • Cool to 4C
  • Add 75 uL Neutralization Buffer for mouse, 50 uL for fish
  • Use 3 uL (1-5) pre PCR reaction

Notes:

  • DNA is suitable for PCR, not Southerns
  • Heating longer than 30 min does not increase [DNA]
  • pH of reagents does not need to be altered
  • DNA yield is similar for tail snips and ear punches
  • Too much tissue destroys PCR
  • Store DNA at 4C or 20C

A Dohlman Lab Protocol

Yeast strains, transformed or untransformed, can be maintained as colonies on solid media at 4° and restreaking every 2 to 4 weeks. Alternatively, strains may be stored at -80 indefinitely. This is preferable in that it reduces the likelihood of accumulating spontaneous mutations.

To make frozen stocks of yeast strains: -Use sterile technique and sterile solutions throughout this method.-

  1. Grow a starter culture at 30 with shaking (250 rpm) until it reaches saturation.

  2. In a 1.8 ml cryotube, mix 0.5 ml of the saturated culture with 0.5 ml of YPD containing 20% glycerol.

  3. Flash freeze the tube in liquid nitrogen and store at -80.

  4. To use, chip out a few pieces of the frozen stock using a sterile pipette tip or sterile toothpick and streak onto a plate containing the appropriate solid media.

  5. Allow the yeast to grow at 30 until colonies appear (2-6 days).

Smoothened (Smo) is a cell surface receptor that, with Patched, mediates sonic hedgehog (Shh) signaling to regulate gene expression through the Gli transcription factors.1 BMS 833923 is an orally bioavailable inhibitor of Smo.2,3 It blocks binding of BODIPY cyclopamine (IC50 = 21 nM) and inhibits Gli activation in cell lines that express wild-type Smo or activated mutant forms of Smo (IC50s = 6-35 nM). BMS 833923 robustly inhibits Shh pathway activity and prevents tumor growth in medulloblastoma and pancreatic carcinoma xenograft models.

(-)-Blebbistatin Sigma B05650-1mg

Info from Cayman:

A stock solution may be made by dissolving the (±)-blebbistatin in an organic solvent purged with an inert gas. (±)-Blebbistatin is soluble in organic solvents such as DMSO and dimethyl formamide (DMF). The solubility of (±)-blebbistatin in these solvents is approximately 10 mg/mL.

(±)-Blebbistatin is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, (±)-blebbistatin should first be dissolved in DMF and then diluted with the aqueous buffer of choice. (±)-Blebbistatin has a solubility of approximately 0.5 mg/ml in a 1:1 solution of DMF:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day.

(±)-Blebbistatin is a selective cell-permeable inhibitor of non-muscle myosin II ATPases.1,2 It rapidly and reversibly inhibits Mg-ATPase activity and in vitro motility of non-muscle myosin IIA and IIB for several species (IC50 = 0.5-5.0 μM), while poorly inhibiting smooth muscle myosin (IC50 = 80 μM).3 Through these effects, blebbistatin blocks apoptosis-related bleb formation, directed cell migration and cytokinesis in vertebrate cells. Blebbistatin is inactivated by UV light,4 which may be particularly important in fluorescent cell imaging applications.

Keep in refrigerator

Description

Brefeldin A is an inhibitor of intracellular protein transport. Incubation of cells in culture with Brefeldin A leads to blockade of protein transport to the Golgi complex (GC) and accumulation of proteins in the endoplasmic reticulum (ER). Addition of Brefeldin A during the last hours of in vitro activation of cells results in enhanced detection of intracellular cytokines. Brefeldin A is effective for enhanced detection of a majority of mouse and human intracellular cytokines; however, it is advised that the investigators evaluate the use and efficacy of this reagent as well as other protein transport inhibitors such as Monensin in their specific assay system.

Applications Reported

The Brefeldin A Solution is supplied at 1000X working concentration in methanol. Prior to addition to the cell cultures, a 1:1000 dilution in the culture media should be made. The final working concentration of the Brefeldin A (at 1x) is 3.0 ug/ml.

Cyclopamine is a naturally occurring Hedgehog (Hh)?specific small?molecule signaling steroidal alkaloid inhibitor, causes a profound inhibition of tumor growth, has significant anti?invasive, anti?proliferative and anti?estrogenic potency in human breast cancer cells [2] [1]. The EC50 of cyclopamine is 10.57 μM, it was identified by an FXR-bla (farnesoid X receptor- b-lactamase) assay [3].

Hh signaling pathway plays a critical role in embryonic development and tumorigenesis [4]. Hh signaling pathway shows saliency in regulating cellular proliferation and differentiation in a wide array of human tissues. It is related to aberrant cell survival in numerous human malignancies, ranging from BCCs and medulloblastomas to small cell lung, gastrointestinal, breast and prostate tumors [1].

Treated with cyclopamine (10 or 20 μM) only and incubated for time periods ranging from 0 to10 days, MCF-7 cells and MDA?MB?231 cells displayed a significant reduction in proliferation rate compared with the control cells on days 3 and 6 (P

Embryoes exposed to cyclopamine resulted in visible external defects, including cyclopia, proboscis formation, microphthalmia, thoracic lordosis, amelia and decreased body size. Examination of gastrointestinal organs revealed severe deficits, including less length of the gut tube and mesenchymal cell numbers in foregut-derived organs. Ectopic structures in duodenum, stomach, and dorsal pancreas were also found [5].

Mfr: Thermo Scientific Chemicals J65864MA

M. Wt: 432.46 Formula: C23H26F2N2O4 Store at +4°C Light sensitive

Solubility: 43.24 mg/mL (100 mM) in DMSO

DAPT is a γ-secretase inhibitor. DAPT reduces Aβ40 and Aβ42 levels in human primary neuronal cultures (IC50 values are 115 and 200 nM for total Aβ and Aβ42 respectively) and in brain extract, cerebrospinal fluid and plasma in vivo. DAPT has no effect on APPα and APPβ levels. DAPT blocks Notch signaling in hybrid human-mouse fetal thymus organ culture (FTOC) and causes ESCs to commit to neuronal differentiation. DAPT can be used in a small molecule cocktail to derive cortical neurons from hPSCs and to maintain hepatocytes in culture. DAPT also promotes the formation of cone photoreceptors in retinal organoids.

From Sigma: Amino Acid Sequence:

Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2

Pituitary hormone which causes darkening skin pigmentation from amphibians to humans. In mammals, it can also have behavioral effects on learning, attention, and memory.

Hormone that stimulates melanogenesis; facilitates learning and memory; affects inflammatory and immune responses and peripheral nerve regeneration.

α-Melanocyte-stimulating hormone (α-MSH) acts as an anti-inflammatory agent via down regulating the production and activity of the pro-inflammatory cytokines interleukin-1 (IL-1), tumor necrosis factor (TNF)-α and IL-6 expressed in various cells of the immune system. It also controls the nitric oxide production associated with inflammation. α−MSH inhibits nuclear factor-κB (NF-κB)-dependent gene transcription and NF-κB pathway induced by TNF and other inflammatory agents. This activity of α-MSH is mediated through the production of cyclic adenosine monophosphate (cAMP) and activation of protein kinase A (PKA) enzyme. α–MSH functions as a potent therapeutics for various conditions resulted through NF-κB activation including, inflammatory diseases, human immunodeficiency virus (HIV) replication in AIDS (acquired immunodeficiency syndrome), and septic shock.[2] α-MSH has an essential role to play in melanin production in animals. α-MSH regulates development of several skin diseases, including cutaneous inflammation and hyper-proliferative skin diseases.[3] Linkage

Derived from ACTH 1-13 Other Notes

Lyophilized from 0.1% TFA in H2O Packaging

1, 5 mg in glass bottle Application

α-Melanocyte stimulating hormone (α–MSH) has been used for following studies: • it has been Intracerebroventricularly (icv) injected to mice for behavioral studies.[1] • to determine the effect of α−MSH on growth of stationary Nb 2 node lymphoma cell cultures.[4] • to determine the effect of α−MSH on leptin secretion in the primary cultures of differentiated adipocytes.[5] • α−MSH promoted melanin production in the B16-F1 cells from murine melanoma cell line.[6] General description

α-Melanocyte-stimulating hormone (α-MSH) is a tridecapeptide, mostly produced by the cells in the brain, pituitary and circulation.[2] Pro-inflammatory cytokines or UV light induced epidermal cells such as keratinocytes and melanocytes synthesize and discharge α–MSH. Poopiomelanocortin (POMC) acts as a precursor for α-Melanocyte-stimulating hormone (α-MSH) production.[3]

General description (from Fisher)

  • All-trans-retinol, commonly known as Vitamin A, is a fat-soluble essential nutrient
  • All-trans-retinol is involved in hormonal signaling via the retinoid receptors
  • It is an important regulator of cell division and apoptosis
  • Deficiency can lead to vision, bone, immune, and skin disorders

Practically insoluble aq. soln. or glycerol; soluble in absolute alcohol, methanol, chloroform,ether,fats and oils.

Can make a 50 mg/mL solution in 95% ethanol, but it's very hard to weigh

From Sigma information sheet:

SOLUBILITY / SOLUTION STABILITY:

  • RE is practically insoluble in water or glycerol. It is soluble in absolute ethanol, methanol, chloroform, ether, fats and oils.
  • RE has been dissolved at 50 mg/ml in chloroform; a clear yellow to orange solution results.
  • Stock solutions of RE (1 mg/ml) were prepared in ethanol, diluted in DMSO under low light conditions and stored at -50°C under nitrogen in brown glass vials.
  • RE solutions (50 μM) were sterile filtered before use.
  • RE both as a solid and in solution is readily oxidized in air and inactivated by UV light.
  • To reduce photodestruction of RE, manipulations of RE solutions can be performed under yellow or red light.
  • Solutions may be stabilized by dissolving in oil, by the addition of anti-oxidant compounds including a-tocopherol or hydroquinone or by conversion to the palmitate and acetate esters.
  • It is recommended to prepare solutions fresh for optimal quality. However, if absolutely necessary, store solutions in the dark under an inert atmosphere at least at -20°C preferably at -70°C
  • Solvents preferred for storage are peroxide-free ethyl ether, acid-free acetone or ethyl acetate.
  • For short term storage, ethanol is suitable as a solvent for spectroscopic analysis.

USAGE / APPLICATION

  • The isolation of retinol from human plasma has been described.
  • RE is an effective antioxidant displaying lipoperoxy radical scavenging activity.
  • The interactions between RE and Vitamin E (a-tocopherol) in suppressing lipid peroxidation were observed in bovine retinal membrane preparations.
  • RE may influence the production of transition vesicles by stimulating the activity of a protein disulfide isomerase-like activity involved in vesicle formation.
  • RE may be involved in immune system mechanisms; an RE deficiency will depress the immune response producing a negative effect on both humoral and cellular immunity.
  • (10 μM) and other retinoid compounds effectively induced sanguinarine and chelerythrine (benzophenanthridine alkaloids) accumulation in suspension-cell cultures of Sanguinaria canadensis in a way similar to fungal elicitation.
  • RE (10 μM) stimulated DNA synthesis and possibly repair mechanisms in Sertoli cells of rat.

GENERAL NOTES

The USP unit of vitamin A (same as the International Unit6) is equal to 0.3 μg of the pure all-trans isomer of retinol which is equivalent to 0.344 μg of all-trans retinyl acetate. RE and its metabolites, including retinoic acid, are part of the retinoid class of compounds, involved in vision, normal embryo morphogenesis and in the regulation of proliferation and differentiation of a number of cell types. Current information and hypotheses on the absorption, transport, storage and metabolism of this fat soluble Vitamin A (retinol) have been reviewed. Studies on RE metabolism including its mobilization and transport in plasma and in tissues via serum and cytosolic retinol-binding proteins have been described.

10 mM

Histone deacetylase Inhibitor

Trichostatin A (TSA), an antifungal antibiotic produced by Streptomyces hygroscopicus, is a potent and specific inhibitor of histone deacetylases (HDACs), which are overexpressed in various cancers and closely correlate with oncogenic factors.

Trichostatin A is active at nanomolar concentrations in mammalian cells. By suppressing the activity of HDACs, it leads to increased histone acetylation, thereby causing highly acetylated histones to accumulate in the cell [2]. This in turn induces enhanced expression of specific genes that elicit extensive cellular morphologic and metabolic changes such as growth arrest, differentiation and apoptosis. At submicromolar concentrations Trichostatin A has been shown to induce apoptosis in diverse cancer cells while exhibiting very low toxicity to normal cells.

TSA is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, TSA should be directly dissolved in 0.1 M HCl (1.3 mg/ml) and then neutralized with PBS (pH 7.2) to achieve the desired concentration or pH. Approximately 0.7 ml of PBS (pH 7.2) is required to neutralize 1 ml of the acidic solution. We do not recommend storing the aqueous solution for more than one day.

Store powder at RT

Make 100 mM stock: 0.166g in 10 mL H2O

___ ___
SKU 02152064-CF
Alternate Names 2-Propyl pentanoic acid; Valproic acid sodium salt; Sodium 2-propylpentanoate
Application Notes Sodium Valproate is reported to cause inositol depletion, activate the ERK pathway, inhibit GSK-3α and GSK-3β. Valproic Acid has been reported to be a potent inhibitor of HDAC (histone deacetylase) in vitro (IC50 = 400 μM for HDAC1), thereby relieving HDAC-dependent transcriptional repression and causes the hyperacetylation of histones in cultured cells. In animal studies, Valproic Acid has been observed to reduce tumor growth and metastasis formation. Additionally, Valproic Acid is reported to activate Wnt-dependent gene expression and to mimic trichostatin A in the inhibition of histone deacetylase. This compound is also an inhibitor of the CYP2C9 enzyme.

From the Sigma web page:

Application

Acridine Orange hydrochloride solution has been used to study autophagic cell death. It has also been used for the staining of chromosomes.

Biochem/physiol Actions

Acridine Orange is a metachromatic dye which can stain DNA, RNA and acid glycosaminoglycans. At low concentration it intercalates into DNA and precipitates RNA. However, at high concentration it denatures and precipitates both RNA and DNA. Acridine Orange is also used to analyze autophagy. It goes into acidic organelles in a pH-dependent manner. At neutral pH, acridine orange gives a green fluorescence and in acidic conditions, it accumulates in the acidic organelle giving a bright red fluorescence.

From use in MBoMS: Use at ~20µM

  • 1.2 µL added to 2 mL in dish

  • incubate 15 min at 37

  • change medium

  • incubate 15 min at 37

  • Replace medium with PBS

  • observe with

    • B excite - G emission: dsDNA
    • G excite - R emission: RNA, ssDNA

Got good results initially, but within minutes, cells started to ball up and pull off the substrate. Will try new PBS first, then a concentration gradient of acridine orange.

Old PBS produced fast shrinking and balling up. Newer PBS was less bad. Now try with non-CO2 medium. Does it interfere with fluorescence?

No cell shrinkage in non-CO2 medium. At short exposure times, there is a background glow, but picking the right exposure takes care of that.

This is time sensitive. The red emission (which should be RNA & ssDNA) gradually fades, or overlies the green emmision (which should be ds DNA)

To stain cells
at particles per cell (between 10 & 50)
add µL Nucleus-RFP

From the mfgr:

CellLight Nucleus-RFP, BacMam 2.0, provides an easy way to label nuclei with red fluorescent protein (RFP) in live cells. Simply add the reagent to your cells, incubate overnight, and the cells are ready to image in the morning.

This ready-to-use construct is transfected into cells using BacMam 2.0 technology, where it expresses RFP fused to the SV40 nuclear localization sequence. You can observe nucleus-RFP behavior in live cells without the cellular toxicity associated with intercalators and label with multiple tracking or tracing dyes to image dynamic cellular processes.

Cells expressing CellLight constructs can also be fixed with formaldehyde for multiplexed imaging using immunocytochemical techniques.

CellLight Technology is:

  • Fast and convenient: simply add CellLight reagent to your cells, incubate overnight, and image—or store frozen, assay-ready cells for later use
  • Highly efficient: up to 90% transduction of a wide range of mammalian cell lines, including primary cells, stem cells, and neurons
  • Flexible: co-transduce more than one BacMam reagent for multiplex experiments or co-localization studies; tightly control expression levels by simply varying the dose
  • Less toxic: CellLight reagents are non-replicating in mammalian cells and are suitable for biosafety level (BSL) 1 handling

BacMam Technology

CellLight Nucleus-RFP, BacMam 2.0, is a fusion construct of SV40 nuclear localization sequence and TagRFP, providing accurate and specific targeting to cellular nucleus-RFP. This fusion construct is packaged in the insect virus baculovirus, which does not replicate in human cells and is designated as safe to use with biosafety level (BSL) 1 in most laboratories. BacMam technology ensures that most mammalian cell types are transduced/transfected with high efficiency and minimal toxicity. This transient transfection can be detected after overnight incubation for up to five days—enough time to carry out most dynamic cellular analyses. Like any transfection/transduction technique, the BacMam method does not transfect/transduce all of the cells with equal efficiency, making it poorly suited to cellular population studies or automated imaging/counting. CellLight reagents are ideal for experiments where cellular or subcellular co-locatization is required, or for cellular function studies that need special resolution.

Toluidine blue

Toluidine blue kdorfman Wed, 03/17/2021 - 16:12

Toluidine blue is a basic thiazine metachromatic dye with high affinity for acidic tissue components.

It stains nucleic acids blue and polysaccharides purple and also increases the sharpness of histology slide images. It is especially useful today for staining chromosomes in plant or animal tissues

Toluidine blue for Madelaine's plant anatomy class

  • 1 % Toluidine blue
  • 0.5% borax

Toluidine Blue Stock Solution:

1g in 100 mL 70% ethanol

NaCl acid solution

1% NaCl aqueous, pH between 2 - 2.5 (w/ glacial acetic acid)

Working toluidine solution

1 part toluidine stock solution : 9 parts NaCl-Acid

Make this solution fresh and discard after use. pH higher than 2.5 will make staining less contrast.

To make: mL working toluidine blue solution,
mix: mL 1% NaCl + glacial acetic acid, pH ~2.25
with: mL 1% toluidine blue in 70% ethanol

Transferrin is a monomeric serum glycoprotein (~80,000 daltons) that binds up to two Fe3+ atoms for delivery to vertebrate cells through receptor-mediated endocytosis.

Once iron-carrying transferrin proteins are inside endosomes, the acidic environment favors dissociation of iron from the transferrin–receptor complex. Following the release of iron, the apotransferrin is recycled to the plasma membrane, where it is released from its receptor to scavenge more iron.

Fluorescent transferrin conjugates can therefore be used with fluorescent LDL to distinguish the lysosomally directed and recycling endosomal pathways.

Liquid Nitrogen is in TC room 371

CO2 (CD75) (75lb cylinders) are in Prep Room 366A

They sell Radnor leak detection solution and dabber bottles but here is a recipe: (see Leak Detection Solution Recipe)

  • 946 ml water
  • 44.4 ml of dish detergent (Dawn)
  • 9.9 ml Glycerol*

The solution becomes more effective if you leave it overnight in an open container. In fact, the longer you leave it, the better the bubbles it produces.

*we've decided glycerin is the same thing as glycerol. It makes the bubbles last longer, which makes them easier to detect
