These two methods work through entirely different principles, but each can achieve significant enrichment of target protein if optimized and applied carefully.
Salting out (also known as salt-induced precipitation, salt fractionation, anti-solvent crystallization, precipitation crystallization, or drowning out) is a purification technique that utilizes the reduced solubility of certain molecules in a solution of very high ionic strength. Salting out is typically used to precipitate … See more Salt compounds dissociate in aqueous solutions. This property is exploited in the process of salting out.
