Introduction
We are going to introduce the wild type yeast to isopropyl alcohol as a stress to see how it reacts if at all.
Materials
- 100% Isopropyl alcohol
- Room temp
- Wild Type yeast tube
- BY4735
- Sterile water
- 96 well plate
- 12 microcentrifuge tubes
Procedure
Diluting the Isopropyl alcohol
- Compute the volume of your 100% isopropyl to achieve a dilution of 50%, 10%, and 5%.
Creating Stock Solutions
- In the first microcentrifuge tube add 100ul of 100% isopropyl.
- 2In the second microcentrifuge tube add 40ul of 100% isopropyl to 60ul of sterile water.
- 3In the third microcentrifuge tube add 20ul of 100% isopropyl to 80ul of sterile water.
- In the fourth microcentrifuge tube add 10ul of 100% isopropyl to 90ul of sterile water
- In the fifth microcentrifuge tube add 4ul of 100% isopropyl to 96ul of sterile water
- In the sixth microcentrifuge tube add 2ul of 100% isopropyl to 98ul of sterile water
- In the seventh microcentrifuge tube add 2ul of 50% isopropyl to 98ul of sterile water
- In the eighth microcentrifuge tube add 4ul of 10% isopropyl to 96ul of sterile water
- In the ninth microcentrifuge tube add 2ul of 10% isopropyl to 98ul of sterile water
- In the tenth microcentrifuge tube add 4ul of 5% isopropyl to 96ul of sterile water
- In the eleventh microcentrifuge tube add 2ul of 5% isopropyl to 98ul of sterile water
- In the twelfth microcentrifuge tube add 100ul of sterile water for the control
Mixing diluted isopropyl and yeast cells
- Add 50ul of wild type yeast to each well labeled 1-12
- Starting in well 1 add 50ul of the contents of microcentrifuge tube 1
- Repeat this process with microcentrifuge tubes 2-12 adding 50ul in their respected wells labeled 2-12
