1. Introduction 

Ion exchange chromatography(IEC)is a very effective method for the separation and purification of biomolecule. The method mainly relies on the interaction between positive and negative charges, and uses the charge properties and differences of different biological molecules under specific conditions to separate them. It has the characteristics of high load, good resolution, controllable condition and easy scale-up. It has been widely used in medicine, chemical industry, metallurgy, food and other fields.
IEC resin is composed of three parts: (1)Cross-linked agarose matrix, that has the characteristics of porous, hydrophilic and good chemical stability; (2)Functional groups fixed to the matrix, which are electrically charged groups, determining the properties of the IEC resin; (3)An ion (called an equilibrium ion) that has an opposite charge to the functional group and can be reversibly bound to the functional group.
The Big Beads series resin are coupled with various functional groups on the agarose base frame with high particle crosslinking. The large particle base can tolerate samples with poor clarity, it is not easy to plug the column, and the flow velocity is fast, suitable for processing large samples in a short time.
