Question

Quizplus · Accepted Answer

Fractionation with varying salt concentrations and centrifugation is the most common method used to separate proteins based on their solubility and size. This process involves changing the salt concentration of the solution to cause different proteins to precipitate out of solution and be separated by centrifugation. It is a simple and effective way to remove unwanted proteins and purify the desired protein.
