Zusammenfassung:In certain embodiments, the present invention provides a method of purifying a monomeric monoclonal antibody from a mixture which comprises the monomeric monoclonal antibody and one or more contaminants, comprising: a) subjecting the mixture to cation exchange chromatography (CEX) matrix, wherein the monomeric monoclonal antibody binds to the CEX matrix; b) contacting the CEX matrix with a wash solution at a pH which is between about 7 and about 7.8; c) eluting the monomeric monoclonal antibody from the CEX matrix into an elution solution, thereby purifying the monomeric monoclonal antibody.
