Abstract
A method for the purification of immunoglobulins by ion exchange chromatography is described. The chromatographic method uses a weak ion exchange resin and a single step elution process for the purification of an immunoglobulin. Additionally a method for the determination of the salt concentration for the single step elution of an immunoglobulin from an ion exchange resin is described.
