  • Cell culture - Gal4-EED/luc for luciferase activation experiment
  • Passage cells 1:4 (T-75 flasks)


Cell culture

  • Make fresh growth medium: DMEM, 10% FBS, 1% pen-strep
  • Set up 2x 6-well plates for Gal4-VP64 transfections
    • 6 wells dox- (3 will be transfected, 3 not) --> 2.5E5/well
    • 6 wells dox+ (3 will be transfected, 3 not) --> 2.5E5/well
  1. Harvest cells: Follow steps 1-9 of Passaging Adherent Cells protocol.
    Note: cells are ~75% confluent, so at this point you will have ~7.5E5/ mL = ~7.5E6 in 10 mL.
  2. Calculation 2: How much growth medium used per unique plate? 6 (+1) wells x 4 mL = 28 mL growth medium
  3. Calculation 3: How many cells used per unique plate? 6 (+) wells x 2.5E5 cells = 1.75E6 cells
  4. Calculation 4: How much stock volume of harvested cells = Calc 3? 1.75E6 cells / (~7.5E5/ mL) = 2.3 mL
  5. In a 50 mL conical, add 25.7 growth medium (which is 28 - 2.3)
  6. Add 2.3 mL of harvested cells to the 50 mL conical.
  7. Get a 10 mL pipette and mix the cells by pipetting up and down (>3 times).
  8. Draw up and dispense 4 mL of the suspended cells into each well in the 6-well plate.

Note: Do this whole procedure separately for the dox- and the dox+ cells

  • Also, passage cells 1:4 in T-75 flasks
  1. Get a new T-75
  2. Add 7.5 mL of growth medium to the flask
  3. Add 2.5 mL of harvested cells to the flask
