The CelloPure⁺ CM weak cationic exchanger is a surface-modified, highly crosslinked medium with dextran scaffold structure. It delivers high dynamic binding capabilities and maintains stability even at elevated flow rates. The optimized media's excellent performance presents a substantial chance to boost the throughput of downstream purification. In this ion exchange resin, the Carboxymethyl (CM) functional group is attached to the cellulose beads, which remains charged and maintains consistently high capacity over the entire working range, pH 2 to 13.
