Integration of perfusion cultivation and automated multi-step purification 12 Feature from a continuous Explorer Feature from a multi-step Explorer A continuous and a multi-step Pure A ÄKTApure can accomplish both continuous and multi-step processing 2013-10-22
13
Integration of perfusion cultivation and automated multi-step purification 13 A six-step process was made to run automated All on one system During the time one of the capture columns is loaded the other protein batch is fully purified Every column can be targeted with e.g. step-specific buffers and e.g. gradient elution A continuous campaign 2013-10-22
