Solved in 2 steps
- 7. Name the structure in this imageIII. ISOLATION OF EGG ALBUMIN Carefully separate the yolk from a fresh egg and get half of the egg white. 2. Measure the volume of the egg white, stir, and add 1/10 from its volume of 1N acetic acid and stir. Filter through cheese cloth to break up the membranes. Stir vigorously with a glass rod to speed up the passage through cheese cloth. Prepare 100 mL of 0.M NH4OH/ NH4Cl buffer solution, pH= 4.5. You will use this in step no.6 Add an equal volume of the buffered saturated ammonium sulfate solution to the filtrate in no. 4. After 30 minutes, centrifuge off the precipitate of ovoglobulin. Ovomucin, a glycoprotein responsible for most of the viscosity of egg white, will also be removed in these two steps. Note: Buffered ammonium sulfate solution is prepared by mixing an equal volume of NH4OH/ NH4Cl buffer solution (0.1M, pH= 4.5) and ammonium sulfate solution. 8.To clear (yellow) centrifugate or supernatant liquid, add buffered ammonium sulfate slowly with stirring…3.
