Electrically controlled focusing of proteins and ampholytes between two modified electrolytes. Computer simulation.

Abstract

Properties of the focusing in simple electrolyte systems using four-pole electrophoretic capillary column was evaluated by a computer simulation. Simulated concentration, pH and conductivity profiles confirm the previous experimentally observed features of the technique, i.e., high concentration capabilities, separation of the ampholytes and proteins into individual adjacent zones, sharp profile of zones and presence of only background electrolyte in the zone. Moreover, the influence of the magnitude of the solvolytic fluxes on the position of the zones in the column is demonstrated.
