  • UniMab® Protein A Affinity resins are designed to raise the purification efficiency of monoclonal antibodies (mAb) and recombinant Fc fragment proteins. The resins are based on rigid, mono-sized polymethacrylate matrices with good surface hydrophilicity, minimal non-specific binding and high mechanical strength for fast flow operations. With excellent FC binding selectivity and base stability, UniMab® Protein A Affinity resins have proven its strong properties in many successful applications including bioprocess purification of mAb-drugs in phase III.
