Ammonium sulfate precipitation

Ammonium sulfate precipitation

Ammonium sulfate precipitation is a useful technique as an initial step in protein purifiion because it enables quick, bulk precipitation of cellular proteins. It is also often employed during the later stages of purifiion to concentrate protein from dilute solution following procedures such as gel filtration.
