The present application provides methods of purifying polypeptides having a Fc region, for example, antibodies or antibody fusions, by adsorbing the polypeptides to a Fc binding agent, such as, for example, Protein A or Protein G, followed by a wash with a divalent cation salt buffer to remove impurities and subsequent recovery of the adsorbed polypeptides.

本申请提供了通过将具有Fc区的多肽，例如，抗体或抗体融合吸附到Fc结合剂，例如，A蛋白或G蛋白上，然后用二价阳离子盐缓冲液洗涤，以除去杂质，随后回收被吸附的多肽来纯化所述具有Fc区的多肽的方法。
