Question

Quizplus · Accepted Answer

The addition of ammonium sulfate to a buffered protein solution is a common method used in protein purification to selectively precipitate and purify a certain protein. Different proteins have different solubility levels at different concentrations of ammonium sulfate, allowing for the isolation and purification of a specific protein. Centrifugation is then used to separate the precipitated protein from the rest of the solution.
