Task
- Make dilution of HCL stock solution and Glycine stock solution (made last class)
- Record conductivity and pH solutions
- Make a pH and conductivity curve
- Prepare and run SDS-PAGE Running-Buffer
- Analyze dialyzed solutions from yesterday
Dilutions
- Made 8 dilutions in 14 mL Falcon tubes using the volumes of stock solution and water. For each stock solution
- Diluted ×2, 5, 10, 20, 50, 100, 200, 500.
