Protein A Captarose HL resin is a chromatography resin specifically designed for large-scale processes. Built on the Captarose HF agarose platform, its highly rigid skeleton and well-defined pore structure deliver exceptional pressure resistance and high flow rate performance. The Protein A ligand has undergone specialized optimization to enhance stability while maintaining high affinity for the Fc region. Produced via recombinant E. coli expression with an animal-free manufacturing process, this affinity chromatography resin exhibits stable physicochemical properties, making it ideal for large-scale industrial production. It serves as an optimal choice for purifying monoclonal antibodies, bispecific antibodies, and Fc-fusion proteins.
