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.

WebBoth cation exchange and anion exchange chromatography can provide robust clearance of aggregates. The primary factors that are critical for aggregate clearance are: resin chemistry, binding and elution condition, peak collection and column load factor.
