NMab Protein A Affinity Chromatography Resin
NMab is based on agarose beads, enhanced with our proprietary microsphere modification technology to improve mechanical strength. Combined with our patented Protein A ligand technology, we have successfully developed NMab Protein A affinity chromatography resin with higher binding capacity than UniMab®. In addition to high capacity, NMab offers excellent binding specificity, alkali resistance, and pressure-flow characteristics, making it an ideal choice for antibody customers to reduce mAb purification costs.
