Yeast protein prep

  1. Grow 3-5 ml of yeast culture for each sample.
  2. Collect sample into Eppendorf tubes, freeze with liquid nitrogen to stop protein expression.
  3. To prepare cell lysates, boil the sample for 5 minutes in hot SDS-PAGE sample buffer (50 mM Tris-HCl pH 7.5, 5% SDS, 5% glycerol, 50 mM DDT, 5mM EDTA, complete protease inhibitors).
  4. Spin down at max speed for 1 minute. Collect the supernatant.
  5. Quantify the total protein content in the supernatant by Bradford assay reagent (Bio-rad).
