Strong Cation Exchange Resin (Polymeric) is a strong cation exchange medium based on cross-linked polystyrene-divinylbenzene matrix, with surface-bonded sulfonylpropyl functional groups. Special pore design allows high flow rate without compromising binding capacity or resolution, enabling rapid interaction between biomolecules and functional groups. Features include high mechanical strength, enhanced interactions, high capacity and resolution, and chemical/physical stability.
