Abstract
A system for separating biomolecules by electrophoretic separation including a first separation barrier having a defined molecular mass cut-off disposed in the first electric field area, a first restriction barrier disposed between a first cathode zone and a first separation barrier so as to define a first interstitial volume therebetween, a second restriction barrier disposed between the first anode zone and the first separation barrier so as to define a second interstitial volume therebetween, and a pumping means to provide a sample constituent in a selected one of the first interstitial and second interstitial volumes wherein upon application of the first voltage potential, a selected separation product is removed from the sample constituent through the first separation barrier and provided to the other of the first and second interstitial volumes.
