Publication number: 20190330267Abstract: 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 change that is opposite to the change of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.Type: ApplicationFiled: June 28, 2019Publication date: October 31, 2019Applicant: CSL LimitedInventors: Adam Charlton, Mark Napoli, Paul Smrdelj, Anthony Stowers, Vicky Pirzas, Magnus Schroeder, Ian Walker
