ABSTRACT:
This invention relates to the use of mixed mode chromatography for purification of a protein from a mixture containing other materials, including fragmented or aggregated antibodies, host cell proteins, DNA, endotoxin, and/or virus. This invention further relates to the integration of such a method into a multi-step procedure with other fractionation methods for purification of antibodies or other proteins suitable for in vivo applications.
