Ammonium Sulfate

Ammonium sulfate is a white odorless solid that sinks and dissolves in water, and is routinely used in agriculture as a nitrogen fertilizer. Ammonium sulfate dissociates to form ammonium and sulfate ions in aqueous medium, and it has been used in the preparation of colloidal Coomassie protein stain. It is used in the precipitation or fractionation of proteins/for purification of antibodies and also useful for crystallographic analysis of nucleic acids and proteins.
