Application

Ammonium sulfate has been used in the preparation of ′Blue Silver′ colloidal Coomassie stain for proteins.Ammonium sulfate may be used for the precipitation or fractionation of proteins or for purification of antibodies. It is also useful for crystallographic analysis of nucleic acids and proteins.

General description

Ammonium sulfate is commonly used in agriculture as a nitrogen fertilizer. In aqueous solution, it dissociates to form ammonium and sulfate ions.
