Cation Exchange Chromatography Resin NRPB91, ≥140 mg/mL (CAT#: STEM-AL2-0963-ZJF)

This product is a chromatography medium intended for cation-exchange biomolecule purification. It uses dextran-grafted high-rigidity agarose microspheres as the support phase. The functional chemistry is based on carboxymethyl. The medium is intended for packed-bed chromatography under the conditions stated in the source data. The source data define the applicable flow, pH, and pressure conditions for the supplied configuration. Chemical compatibility information supports equilibration, washing, regeneration, and cleaning workflows where applicable. Storage conditions are specified to maintain the medium before use and between operations. The product can be integrated into laboratory or process purification workflows consistent with its stated separation mechanism.
