Materials
- Prednisone
- Absolute Ethanol
- Yeast Cultures
- Sterile Water
- Corning COSTAR 96-Well Clear Flat-Bottom Assay Plate
- Micropipettes
- Centrifuge Tubes
Equipment
- Incubator set to 30°C
- Molecular Devices SpectraMax Plus 384 Microplate Reader
Protocol
- Make stock solution by vortexing the following:
- 50 mg Prednisone
- 10 ml ethanol
- Dilute down to needed percentages (below) using sterile water.
- In each well, add 50 µl of wildtype yeast strain.
- Using the stock solution (P1), add 20 µl to the first well along with 30 µl of sterile H2O.
- This well should now have 100 µl of total solution.
- Using the stock solution (P1), add 6 µl to the second well along with 44 µl of sterile H2O.
- This well should now have 100 µl of total solution.
- Repeat this process for each set of wells, going down one dilution after each set of two wells.
- Refer to the Well Concentrations chart.
- Dilute pure ethanol down to needed percentages (below).
- In 12 different wells, a new row, add 50 µl of wildtype yeast strain.
- Add the ethanol dilutions to the 12 new wells, using the same process as used above.
- This row will be used to compare the Prednisone treated yeasts’ growth rates.
- Shake all wells at 37°C for 24 hours.
- Plot data and select the Prednisone amount/concentration for the next test that shows results but doesn’t completely kill the yeast cultures.
