摘要：

A simple instrument system combining high-performance capillary electrophoresis (CE) and membrane technology is described. CE fraction collection is successfully implemented using a membrane assembly at the exit end of a capillary to complete the electrical circuit for electrophoretic separation. This membrane assembly consists of a poly(vinylidene difluoride) membrane, a buffer reservoir (two layers of 3 MM Chrom filter-paper) and a stainless-steel plate as the ground electrode. Two model proteins are separated and collected on the membrane. Direct protein sequencing is demonstrated from this membrane after CE fraction collection.
