| 摘要 |
The present application provides methods of purifying Abeta binding proteins having a Fc region, for example, anti-Abeta antibodies or antibody fusions, by adsorbing the Abeta binding protein 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 Abeta binding protein. The present application also features methods of eluting the purified Abeta binding protein as well as the incorporation of the methods within a purification train. Kits comprising components for carrying out the methods and instructions for use are also provided.
