ABSTRACT:
An electrophoresis medium membrane comprises a planar support, a planar cover sheet, and a layer of an electrophoresis gel medium provided between the planar support and the planar cover sheet. The electrophoresis gel medium contains an aqueous polyacrylamide gel, which is prepared by cross-linking polymerization of an acrylamide compound and a cross-linking agent in the presence of water and a compound having at least one carbamoyl group as a denaturing agent (or modifier). The layer of the electrophoresis gel medium has both a predetermined gradual change (gradient) in layer thickness and a predetermined gradual change (gradient) in concentrations of the acrylamide compound and the cross-linking agent.
