Web12 okt. 2016 · Ion-Exchange Chromatography (IEC) allows for the separation of ionizable molecules on the basis of differences in charge properties. Its large sample-handling capacity, broad applicability (particularly to proteins and enzymes), moderate cost, powerful resolving ability, and ease of scale-up and automation have led to it becoming one of the … Web2 jan. 2024 · Ion exchange chromatography is normally employed for the separation of lactoferrin and lactoperoxidase from whey. These proteins have isoelec-tric points above pH 9 and so are positively charged at the pH of whey and can be separated on cation exchange resins, then purified using ultrafiltration (Heeboll-Neilsen et al. 2004).

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.
