UW-Stout/Hydroxychloroquine SP21
Contents
Materials
- Corning COSTAR 96-well clear flat-bottom assay plate
- Wild-type yeast in 2x synthetic complete media at an OD600 of 0.1-0.2
- Hydroxychloroquine, 300 ug/uL solution in sterile water (as calculated in the calibration protocol)
- P20, P200 micropipettors
Equipment
Precautions
Use gloves and safety glasses for this experiment. Hydroxychloroquine is a potent chemical used to treat malaria and some autoimmune conditions. However, side effects include but are not limited to nausea, headache, dizziness, rash.
Calibration Protocol
- This experiment is designed to test the growth response of wild strain yeast cells to various concentrations of hydroxychloroquine, a lysosome disruptor. This is done to find out the most suitable concentration of the torture factor to exert stress on the cells, but not destroy them.

Materials
- Corning COSTAR 96-well clear flat-bottom assay plate
- Wild-type yeast in 2x synthetic complete media at an OD600 of 0.1-0.2
- Hydroxychloroquine, 300 ug/uL solution in sterile water
- P20, P200 micropipettors
Protocol
- Vortex the yeast culture briefly to resuspend the yeast cells.
- Set up seven wells aliquoting 50uL of the stock hydroxychloroquine and 50uL of yeast culture. Use the seventh well for the wild-type yeast strain.
- The final concentration of hydroxychloroquine is 300ug/mL.
- To measure cell growth over a period of 24 hours, set up the plate reader as follows:
- Temperature: 30°C
- Mode: Kinetic
- Wavelength: 600 nm
- Interval: 5 minutes
- Total run time: 24 hours
- Shake before reading: 30 seconds
- Transfer the assay plate to the reader and read for 24 hours.
- Note: Repeat the experiment a few times to account for natural variation.
