ELUTION OF MONOCLONAL ANTIBODIES IN PROTEIN A AFFINITY CHROMATOGRAPHY

摘要

The invention provides a method for eluting a monoclonal antibody from a Protein A affinity chromatography column to which the monoclonal antibody is bound comprising a) contacting the affinity chromatography column with an elution buffer comprising a poly (ethylene glycol) polymer; b) collecting one or more fractions containing the monoclonal antibody obtained from step (a) c) combining the fractions obtained from step (b) to form an elution product pool.
