Which substance is used to fractionate proteins based on differences in their solubility as a function of salt concentration?
A)Cellophane.
B)Sodium dodecyl sulfate.
C)Phenylisothiocyanate.
D)Ammonium sulfate.

Question

Quizplus · Accepted Answer

Ammonium sulfate is a salt that can be used to fractionate proteins based on their solubility. As the concentration of ammonium sulfate is increased, the solubility of proteins decreases, allowing for separation based on differences in solubility. Cellophane and phenylisothiocyanate are not commonly used for protein fractionation, and sodium dodecyl sulfate is typically used for denaturing and separating proteins based on size.
