Our alkaline-stable recombinant protein A ligands are immobilized onto our proprietary polymethacrylate base matrices to provide cost-effective solutions for fast-processing of monoclonal and polyclonal antibodies, bispecific antibodies, and Fc fusion constructs with high quality.
IA122: UniMab 50 HC Protein A Affinity Resin
UniMab® 50 HC protein A resin is a high-performance, alkali-resistant recombinant Protein A affinity chromatography medium developed by NanoMicro using its proprietary technologies. The resin is made with monodisperse, crosslinked polymethacrylate matrix, proprietary surface modification and epoxy coupling chemistry for bonding Protein A. It is suitable for the separation and purification of monoclonal antibodies and recombinant protein biological macromolecules containing Fc domains. UniMab® 50 HC has high mechanical strength, low back pressure, good chemical stability, and strong alkali resistance. Even at high flow rates, it can still maintain a high dynamic adsorption capacity, which can significantly improve productivity for laboratory preparation to pilot test and industrial production. Table 1 lists the basic characteristics of this protein A resin:

The engineered protein A in UniMab® 50 HC protein A affinity resin is manufactured with animal free raw materials.
UniMab® 50 HC protein A affinity resin provides reliable all around performance, low protein A leakage, high binding capacity and a useful effective working range requiring a residence time of at least 3 minutes (equivalent to a typical running speed of 300 cm/hr). It is available in bottled (20% ethanol at 60% slurry concentration) or pre-packed column packaging.
