Use of mixed mode chromatography for purification of an antibody from an antibody mixture, for example) a Pichia pastoris fermentation mixture containing impurities such as host cell proteins and DNA is described Mixed mode chromatography is used instead of protein A chromatography and presents certain advantages over protein A chromatography Furthermore, the integration of such a method into a multi-step procedure with other fractionation methods for purification of antibodies suitable for in vivo applications is provided. |
