| Purification of greater protein mass, from higher fermentation titers can lead to bottlenecks downstream both in terms of unit operations capacity and subsequent preparations of buffers. A unique disposable flow through anionic membrane adsorber, is described .This is designed to replace the anion exchange column in a traditional chromatography polishing template. The characteristics of the support membrane, unique gel surface coating and device flow distribution are described. A unique feature of the membrane chemistry is the ability to bind impurities at high conductivities (14mS) eliminating the need for cation pool dilution .Data is shown from MAB feedstocks where purity targets of HCP to <10 ppm, DNA >3 LRV, Virus >4 LRV were achieved. |
