- Preparation of Apoprotein:
- 24.3 mg of Tris was added to 4 mL of water to make a 0.05M solution to dissolve 200 mg of myoglobin
- 3.36 g of Sodium Bicarbonate was dissolved in 4L of H2O to make a 10 mM dialysis buffer
- The pH of the Tris solution was brought down to 2.3-2.5 at 0°C before 2-butanone extraction was performed
- 2-butanone was placed on ice for the extraction
- Acid/2-butanone extraction was performed on the protein solution with equal parts 2-butanone and protein
- The aqueous extract was then added to a dialysis cassette and placed in the dialysis buffer in the 0°C cold room and will sit overnight
- Approximately 3 mL of aqueous extract was extracted overall
