It is also used in many biological applications. It is mostly used in protein purification processes because ammonium sulfate is an inert substance and is not easily reacted with other biologically active substances. It can protect protein activity to the greatest extent during purification.
In addition, the solubility of ammonium sulfate is extremely high. Well, it can form a high salt environment, ready for protein precipitation and subsequent high salt purification. The solubility of ammonium sulfate at zero degree and normal temperature is quite different. The following is the molar concentration of ammonium sulfate at different temperatures at two temperatures.
