Abstract
A method for producing gradient gel medium membrane for electrophoresis in which a monomer solution having a continuous concentration gradient and a polymerizing reaction initiator solution are supplied to a coating head as a gel forming solution for electrophoresis while mixing the monomer solution and the polymerizing reaction initiator solution with each other so as to coat a moving web with the gel forming solution. The coating liquid is supplied onto a moving web through the coating head in such a manner so that the flow of the coating liquid extends continuously in the direction of width and is continuously reduced in the direction of thickness along the coating head from its supply inlet to its slot opening.
