Diamond SP Mustang XL - Strong Cation Exchange Resins

Ion exchange (IEX) chromatography 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.
IEX resin is composed of three parts:
(1) Cross-linked agarose matrix, that has the characteristics of porous, hydrophilic and good chemical stability, through the modification to traditional agarose molecules, it has stronger mechanical properties, which is called high rigid agarose, namely Diamond matrix.
(2) Functional groups fixed to the matrix, which are electrically charged groups, determine the properties of the IEX 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.
Based on a high-rigidity agarose microsphere, Diamond SP Mustang XL is obtained by firstly coupling dextran long chain, and then cross-linking sulfopropyl groups on the dextran molecules. This structure reduces the steric hindrance effect between biomolecules and ligands, greatly increasing the dynamic binding capacity of the target molecules.
