color mixing workshop LLCPK GFP-alpha tubulin cells (have a lot of vacuoles, though)

Made up 2x staining solutions in Fluorbrite:

Nuc blue: 20 uL/2 mL; 40 uL/2 mL

Mitotracker red: 250 nM, 500 nM

Cells incubated in coverslip dish 1 mL nuc blue staining solution + 1 mL mitotracker staining solution.

Hi nuc + Hi MT
Hi nuc + low MT
low nuc + Hi MT
low nuc + low MT

Warm all media first, then remove the F10-Hams, replace with appropriate staining solutions. Keep cells in incubator for 15 min, check...


Color Mixing with Inks CMY(K)

1:15 (approximate) yellow printer ink in water 1:200 magenta 1:200 cyan

we pipetted various ink amounts onto parafilm to mix colors - final volume of droplets = 100ul


Additive Mixing with Light (RGB Flashlights) Flashlights made by RaySoar LED Limited Company

Staining solution NucBlue + Mitotracker

Staining solution NucBlue + Mitotracker kdorfman Fri, 09/30/2022 - 13:47

Staining Solution

  • 1 mL fluorobrite
  • 10uL NucBlue
  • 1 uL Mitotracker red

Staining Protocol

  • Remove pink medium from cells (~2.5 mL)
  • Replace with Staining Solution
  • Rock dish to make sure solution covers the surface
  • Incubate ~15 min at 37C

Observation Protocol

  • Find cells with phase
  • Switch to fluorescence
    • turn on arc lamp
    • turn off white light
    • open mechanical shutter (CLOSE WHEN NOT LOOKING AT CELLS! THEY BLEACH!)
    • open electronic shutter
    • turn filter cube to UV to see blue nuclei
    • turn filter cube to G to see red mitochondria

FIRST DAY

Pipetting Exercise

DNA Extraction

  • Extract DNA from fish fin clips with HotSHOT DNA extraction prep

    • 50 uL alkaline lysis reagent per rxn
    • 50 uL Neutralization buffer per rxn
    • Aliquot 1 mL of each per pair
  • Rolf brings 20 fin clips

  • Students work in pairs, doing 4 clips per pair.

Set up PCR reactions

  • Use Qiagen Taq PCR Master Mix Kit

  • Dilute primers from Rolf's lab for GFP (final 0.4 uM in mix)

  • Each 25 uL reaction contains:
    • 12.5 uL 2X Master mix
    • enough primer to make 0.4 uM
    • 5 uL DNA
    • water to 25 uL
  • We make 900 uL Master Mix with primers
    • 3.6 uL each 100uM primer
    • 450 uL 2x master mix
    • 446.4 uL water (to final volume 900 uL)
  • Each individual student tests all 4 of the DNA samples
    • 20 uL per rxn
    • aliquot 180 uL per pair

Make enough master mix for 9 reactions per pair

PCR program (finclip in Main menu):

Step time (min) temp comment
1. Initial denaturation 2 94
2. denaturation 0.5 94
3. annealing 0.5 55 ~4C below primer Tm
4. extension/elongation 0.5 72 or one min per kb 1
5. go to 2 38 times
6. final extension 5 72
7. hold forever 15 can cut short and put into fridge

SECOND DAY

Gel

BLAST

Use primer sequences?

Analyze Gel

  • check bands in blue light
  • take cell phone photo
  • send to Rolf with documentation

  1. 45 sec is better for mcherry; can use 45 sec to 1 min for GFP. EGFP and mcherry amplicons are ~500 BP ↩︎
