Harvesting AAV by tangential flow filtration using reverse asymmetric membranes
Biotechnology Progress, EarlyView.Abstract Efficient bioreactor clarification for harvesting virus particles is often challenging. Tangential flow filtration is attractive as it can be easily adapted for batch and perfusion operations. Here the feasibility of using reverse asymmetric hollow fiber membranes, where the more open support structure faces the feed stream, has been ...
