Abstract
A method of making an electrophoresis sheet composed of two sheet members formed of a non-conductive organic polymer film and disposed to stand facing each other, spacers having predetermined thicknesses disposed at both edge portions between the two sheet members, and an electrophoresis gel membrane of uniform thickness provided with slots extending from an upper edge portion towards a center and grasped between the two sheet members, comprises the step of forming the slots by pushing a cutting blade member against a gel membrane web before the gel membrane web is grasped between the sheet members. The cutting blade member is composed of a combination of a single linear transverse blade having a plurality of cutaway portions and disposed to extend in a transverse direction of the gel membrane web, with a plurality of linear longitudinal blades continuing to the linear transverse blade at both ends of each of the cutaway portions.
