Zusammenfassung:	Combinations of different chromatography modalities with particularly refined conditions significantly reduce acid charge variants in a preparation of monoclonal antibodies. The process for reducing acid charge variants utilizes a combination of anion exchange and hydrophobic interaction chromatography, followed by cation exchange chromatography polishing, whereby the levels of acidic or basic charge species of the monoclonal antibodies may be modulated to a desired level.
