Monoclonal Antibody Purification with a High Capacity Protein A Resin

“Protein A resins constitute a substantial cost in state-of-the-art mAb purification processes. Factors such as operating cycles, capacity, and mAb titer can have an impact on total costs associated with mAb purification. The purification of a monoclonal antibody from crude feed stock using TOYOPEARL® AF-rProtein A HC-650F, a high capacity protein A resin from Tosoh Bioscience, show that this particular high capacity protein A resin delivers highly pure antibodies at yields approaching 90%.”
