Q XL Big Beads - Strong Anion Exchange Resins

Ion exchange (IEX) chromatography is a very effective method for separation and purification of biological molecules. The method mainly relies on the interaction between positive and negative charges, and uses the nature and difference of the charges carried by different biomolecules under specific conditions to separate. It has the characteristics of high load capacity, good resolution, controllable conditions and easy amplification. It has been widely used in medicine, chemical industry, metallurgy, food and other fields.
The ion exchange resin is composed of three parts:
(1) Cross-linked mesh base frame, which is porous, hydrophilic and chemically stable.
(2) The functional group fixed on the base frame, which is a charged group, determining the nature of the ion exchange chromatography 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.
XL Big Beads series resin are obtained by firstly coupling linear dextran molecules on the large particle highly cross-linked agarose base, before coupling various functional groups to the dextran molecules. This structure reduces the steric hindrance among biomolecules and can greatly increase the binding with target molecules. The large particle base can tolerate samples with poor clarity, reducing the possibility of column blockage. Its fast flow velocity is suitable for processing large samples in a short time.
Q XL Big Beads is a strong anion exchange resin, which can directly capture biological macromolecules from the feed stock. It enjoys high binding capacity and fast flow velocity.
