Japanese name: アフィニティ精製レジン（Protein A）
Protein A resins capture antibodies and Fc fusion proteins through their Fc region. They are the core capture step of monoclonal antibody platforms, pulling the product out of the harvest in one step. Buyers compare base matrix (agarose or rigid polymer), dynamic binding capacity, tolerance to NaOH cleaning in place (CIP), residence time and linear flow rate, and how gentle the elution pH is for acid-sensitive molecules. Browse the products we track below, with their makers and the Japanese companies that sell them.
