Application

Ammonium sulfate helps in quick precipitation of celluar 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.Ammonium sulfate has been used
  • in the preparation of ′Blue Silver′ colloidal Coomassie stain for proteins.
  • to precipitate the Shiga-like toxin from the culture supernatant.
  • for precipitaion of viral particles from the culture supernatant.

Features and Benefits

  • Heavy metals (as Pb): ≤2 ppm
  • Free from DNase, RNase, and protease

General description

Ammonium sulfate is a versatile inorganic sulfate salt, plays crucial role in biochemical research, molecular biology, and cell culture. It serves as an indispensable tool for purifying antibodies and precipitating or fractionating proteins. Furthermore, it is instrumental in crystallographic analysis of nucleic acids and proteins and also used as a nitrogen supplement in synthetic laboratory media. Our premium-grade Ammonium Sulfate is meticulously crafted to be DNase, RNase, and Protease-free, ensuring its suitability for cutting-edge research.
