Ion-Exchange Chromatography: An Easy Introduction to the Basics

WebIon exchange chromatography (IEX or IEC) separates proteins according to the strength of their overall ionic interaction with either negatively of positively charged groups on a resin. By manipulating buffer conditions (e.g., ionic strength and pH), molecules of greater or lesser ionic character can be bound to or dissociated from the solid phase material. WebA second sub-category of liquid chromatography is known as ion-exchange chromatography. This technique is used to analyze ionic substances. It is often used for inorganic anions (e.g., chloride, nitrate, and sulfate) and inorganic cations (e.g., lithium, … 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 logitech c922 set up
