Ammonium Sulfate Precipitation Protocol

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. ...

What Is Sulfate Precipitation? (with picture)

 · Sulfate precipitation occurs when a precipitation reaction is brought on by adding a sulfate salt to a certain solution. Most of these precipitation reactions are concerned with extracting proteins from a solution. Two major methods are used in sulfate precipitation, one of which is referred to as “salting out” and requires excessive amounts of salt to be added to a solution to cause the ...

Abstract. Addition of appropriate amounts of salts, such as ammonium or sodium sulfate, causes precipitation of IgG from all mammals, and can be used for serum, plasma, ascites fluid, and hybridoma culture supernatant.Although such IgG is usually contaminated with other proteins, the ease of these precipitation procedures coupled with the high yield of IgG has led to their wide use in ...

Solubility Rules and Identifying a Precipitate

Barium chloride and potassium sulfate are both ionic compounds. We would expect them to undergo a double displacement reaction with each other. BaCl 2 + K 2 SO 4 BaSO 4 + 2 KCl By examining the solubility rules we see that, while most sulfates are soluble, barium sulfate is not. Because it is insoluble in water we know that it is the precipitate.
