In bulk protein purification, a common first step to isolate proteins is precipitation with ammonium sulphate (NH 4) 2 SO 4. This is performed by adding increasing amounts of ammonium sulphate and collecting the different fractions of precipitate protein.rotein purification is a series of processes intended to isolate one or a few proteins from a complex mixture, usually cells, tissues or whole organisms.
