Which separation technique exploits the solubility differences of proteins?
A) centrifugation
B) salting out
C) dialysis
D) ion-exchange chromatography

Question

Quizplus · Accepted Answer

Salting out is a technique that involves adding large amounts of a salt, such as ammonium sulfate, to a protein solution. This reduces the solubility of the proteins, causing them to precipitate out of the solution. Different proteins have different solubility thresholds, so this technique can be used to separate proteins based on their solubility differences.
