Publication number: 20160185816Abstract: The present invention relates to improved processes for purifying polypeptides of interest by increasing the amount of a polypeptide of interest bound to an ion-exchange matrix relative to the amount of one or more impurities bound to the ion-exchange matrix. This effect is achieved by adding a chemical compound in the process which by also binding to the ion-exchange matrix due to a charge that is opposite to the charge of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.Type: ApplicationFiled: July 30, 2015Publication date: June 30, 2016Applicant: CSL LimitedInventors: Adam Charlton, Mark Napoli, Paul Smrdelj, Anthony Stowers, Vicky Pirzas, Magnus Schröder, Ian Walker
