UniCM-30S Weak Cation Exchange Chromatography Resin

NanoMicro UniCM-30S weak cation exchange chromatography resin is based on a polymer matrix that has been surface-modified with hydrophilic groups and then coupled with ion exchange ligands. It offers excellent biocompatibility and physicochemical stability for biomolecules, significantly improving purification efficiency. It is ideally suited for the purification of small biomolecules such as small proteins, peptides, nucleic acids, and antibiotics.

UniCM-30S features a hydrophilic surface modification that provides low non-specific binding, high resolution for small molecules, and high binding capacity. Key technical parameters are listed below:
