Ion-exchange chromatography of proteins
WebSeveral side-chain groups of the amino acid residues in proteins are ionizable (e.g. lysine or glutamic acid) as are the N-terminal amino and C-terminal carboxyl groups and so proteins are charged molecules. This characteristic can be used to separate different proteins by ion-exchange chromatography. Types of Exchangers WebIon-exchange chromatography is the most popular chromatographic method for separation of proteins. It is a versatile and generic tool and is suited for discovery of proteins, high …
