  • METHODS FOR PURIFYING ANTIBODIES
    Publication number: 20230046182
    Abstract: The present invention relates to a method of purifying a recombinant polypeptide from Host Cell Proteins (HCP), the method comprising: (a) applying a solution comprising the recombinant polypeptide and HCP to a superantigen chromatography solid support, (b) washing the superantigen chromatography solid support with a wash buffer comprising caprylate and arginine; and (c) eluting the recombinant polypeptide from the superantigen chromatography solid support.
    Type: Application

  • METHODS FOR PURIFYING RECOMBINANT POLYPEPTIDES
    Publication number: 20210054051
    Abstract: A method of purifying a recombinant polypeptide from a Host Cell Protein (HCP), wherein the amino acid sequence of the recombinant polypeptide comprises a cathepsin L cleavage site is provided. The method includes: (a) applying a solution containing the recombinant polypeptide and HCP to a superantigen chromatography solid support, (b) washing the superantigen chromatography solid support with a wash buffer containing caprylate and arginine; and (c) eluting the recombinant polypeptide from the superantigen chromatography solid support. A method of purifying an anti-OX40 antigen binding polypeptide from a Host Cell Protein (HCP) is also provided.
