The ability of membranes to separate proteins on the basis of                   molecular weight is much less than would be expected from the                   properties of the membranes alone.  Generally proteins must                     differ by at least an order of magnitude to be efficiently                      separated by ultrafiltration.  Various phenomena have been                      suggested in the literature to explain this, including such                     things as gel-layer formation, adsorption of the protein on the                 membrane, too broad a pore size distribution, formation of                      protein complexes, etc.  This project will focus on a systematic                experimental variation of the most important parameters affecting               the membrane separation of two proteins with the goal of                        identifying the actual phenomena of most importance.  If                        successful, this project should lead to the design of improved                  membranes and improved operating procedures for more efficient                  membrane separation of proteins.  This accomplishment would help                remove a major engineering roadblock to the commercialization of                biotechnology advances of the last decade.
