WebWe describe two methods of high-throughput protein concentration and buffer exchange: one using ammonium sulfate precipitation and one using micro-concentrating devices based on membrane ultrafiltration. We evaluated the efficiency of both methods on a set of 18 randomly selected purified proteins from Shewanella oneidensis. WebSartorius tangential flow filtration (TFF) cassettes provide high-performance separation in various upstream and downstream bioprocessing unit operations. They are available in a range of molecular weight cut-offs and micron range, from lab scale to process scale, in single-use and re-usable formats. When used together with associated TFF ...
