SEPARATION OF RECOMBINANT POLYCLONAL ANTIBODY MULTIMERS WITH MINIMAL SEPARATION OF MONOMERS |
摘要 |
The invention provides a method for removing multimers from a preparation of recombinant polyclonal antibodies (rpAbs) while maintaining the ratio of monomers within a narrow range. The invention provides a method of separating recombinant polyclonal antibody multimers with minimal separation of monomers comprising subjecting a mixture comprising a plurality of monoclonal antibodies to at least one separation process selected from the group consisting of multi-modal chromatography, apatite chromatography, and hydrophobic interaction chromatography thereby producing an antibody monomer preparation that is substantially free of multimers. |
