Ion Exchange Chromatography Explained: Techniques & Uses

Ion exchange chromatography (IEX) is a powerful technique used for the separation and purification of proteins based on their charge. It exploits the interaction between charged molecules in a sample and oppositely charged moieties in the stationary phase of the chromatography matrix. IEX is consistently used for protein purification for several reasons, including its tunable selectivity, versatility, high selectivity, high capacity and efficiency, compatibility with biological samples, scalability, cost-effectiveness, and complementarity with other techniques.

This eBook will guide you through the intricacies of IEX, exploring the interplay between charged molecules and oppositely charged ligands on chromatography beads. We'll delve into the pivotal role of pH in IEX, affecting both the resin's charge and the protein's behavior. Discover how pH influences a protein's charge and its interaction with the IEX resin. Also covered in this eBook are practical aspects like selecting the perfect resin and optimizing IEX procedures. Learn about the different types of resins, their properties, and how to choose the best one for your specific needs.
