Computers, servers, etc.

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.

Optima Plate Reader

Optima Plate Reader kdorfman Tue, 01/17/2017 - 19:12

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 inside the user dialog box before running a script!

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. (!?!)

Table style

"Table" no well numbers, or wavelength indicators, etc. Just the results in plate layout form.
"Table with well numbers in plate layout style" USE THIS
"Table with well numbers" puts the well IDs next to the reading (Very hard to read)

Script mode

For i = 1 to 72 This is the counter
id 1 = "BOD1" BOD1 is the file name

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

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.

Autoclave

autoclave manual

Always put a piece of autoclave tape on the item or container so you can tell if it was exposed to the steam.

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:

Largest volume (mL) Minimum time (min)

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.

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

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.

From the manufacturer: "Methylation of DNA at cytosine residues in mammalian cells is a heritable, epigenetic modification that is critical for proper regulation of gene expression, genomic imprinting and development (1,2). Three families of mammalian DNA methyltransferases have been identified: DNMT1, DNMT2 and DNMT3 (1,2). DNMT1 is constitutively expressed in proliferating cells and functions as a maintenance methyltransferase, transferring proper methylation patterns to newly synthesized DNA during replication."

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.

How to fix cells and tissues

Fixing adherent cells

Fixing adherent cells kdorfman Thu, 05/21/2020 - 17:39

To fix the cells grown on a coverslip

  • Work in a fume hood
  • Gently rinse cells 2X in warm PBS (remove medium, add PBS, repeat)
  • Leave cells in this PBS—until you add the fixative.
  • Remove final PBS rinse, add about 1 mL of fixative to the cells
  • Fix cells in hood for 10 mins.
  • Rinse cells by dunking each coverslip in 3 beakers of PBS-Tween-Azide, 10 X per beaker.
  • Place coverslip back in dish with fresh PBS-Tween-Azide
  • If you are not staining immediately, store cells in PBS-Tween-Azide in fridge.

Remember:

  • Work in the fume hood
  • Wear gloves!
  • Keep track of which side of the coverslip the cells are on
  • Discard used fixative in the appropriate hazardous waste container in the hood.

Myosin inhibitor

(-)-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.

Note green fluorescent crystals seen in a 75µM solution.

Brefeldin A

Brefeldin A kdorfman Tue, 11/12/2019 - 20:48

Fisher 00-4506 1000x solution

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.

*Requirements:**      * Acid washed coverslips stored in 100% ethanol.

  • ConA 0.5 mg/mL. 

  • Large petridishes to store the coverslips.    

  Procedure:

  • Flame the acid-washed coverslips and cool for 10 sec.    (Make 9-­‐14 coverslips     at a    time    to save time.)

  • Place the coverslips on top of the    large petri dish.     

  • Thaw the conA from the freezer and dilute to 0.5 mg/mL 
  • apply around 400uL the first two coverslips 

  • Wait for 10 sec. 

  • Tilt the coverslips and suck out the excess ConA 

  • Repeat the same for all the coverslips. 

  • Cover the petri dish with another lid of petri dish and allow a small opening to dry.

  • If possible,use a vacuum pump  to dry it faster.   

The process usually takes 15 minutes and drying takes half an hour. 

Storage:

  * In a petri dish, place the coverslips on top of a clean kimwipe with the conA surface facing up.

  • Cover with the lid. 10 min before needed, UV sterilize them.

  • Alternatively, UV sterilize all of them after drying and open the dishes only in aseptic conditions or inside hood.

Importazole is an inhibitor of importin-β transport receptors.

During interphase, the transport receptor importin-β carries cargoes into the nucleus, where RanGTP releases them. Importazole somehow disrupts the importin/RAN interaction. Importazole is selective among other transporters. Compounds are imported into, but not out of, cells.

A cell-permeable diaminoquinazoline compound that selectively blocks importin-β-mediated nuclear import of NLS bearing cargos in a reversible manner.

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

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]

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.

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.

  • 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)

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.
