The following table shows the weight (g) of ammonium sulfate to be added to one litre of solution to produce a desired change in the concentration (% saturation) of ammonium sulfate. Precipitation of proteins is conventionally carried out at 0°C to avoid possible denaturation of proteins, although the % saturation values shown in the table are
tionating antisera is precipitation in the cold with half-saturated ammonium sulfate. The procedure is simple and inexpensive, and the resulting crude antibody fractions from the antisera of a number of animal species have been successfully used in many areas of im-munology. In this laboratory these crude frac-tions have been conjugated with

Ammonium sulfate precipitation is a common method for protein purification by precipitation. As the ionic strength of a solution increases, the solubility of proteins in that solution decreases. Ammonium sulfate is extremely soluble in water due to its ionic nature, therefore it can “salt out” proteins by precipitation.
Ammonium sulfate precipitation is a method of protein purification by altering the solubility of protein. Ammonium sulfate is commonly used due to its high solubility that allows salt solutions with high ionic strength. At sufficiently high ionic strength, the protein will be almost completely precipitated from the solution. Differential precipitation of proteins by ammonium sulfate is one of

Ammonium sulfate precipitation is one of the most commonly used methods for large and laboratory scale protein purification and fractionation that can be used to separate proteins by altering their solubility in the presence of a high salt concentration.
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.

Description Ammonium sulfate precipitation is one of the most commonly used methods for protein purification from a solution. In solution, proteins form hydrogen bonds with water molecules through their exposed polar and ionic groups. When high concentrations of small, highly charged ions such as ammonium sulfate are added, these groups compete with the proteins to bind to the water molecules
