Abstract
The present methods relate to the isolation and concentration of proteins using cross-flow membrane filtration, and to proteins produced by such methods. A feature of the method is that the protein of interest is retained by a cross-flow membrane under certain conditions that promote retention, while under other condition the protein passes through the membrane.
