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. WebIon-exchange chromatography [ edit] DEAE-C is a weak anion exchanger. This exchange is utilized to separate proteins that have faintly differing charges. Like all anion exchangers, the resin carries a positive charge that interacts favorably with negative charges. The positive charge of DEAE cellulose is due to a protonated amine group.
