ABSTRACT:
An electrophoresis apparatus comprises a gel sheet device composed of spacers disposed between two films at side edges thereof, a gel membrane provided within a space formed between the two films by the spacers, and sample-pouring portions provided near an upper edge of the gel membrane. Two supporting members hold the gel sheet device therebetween, and a gap-forming member contacts edges of at least one surface of the gel sheet device. Each sample-pouring portion is adapted to sample pouring into a space formed by the films, a shark's teeth comb, and the upper edge face of the gel membrane. The gap-forming member remote from an upper buffer solution vessel is provided such that an inner edge of a gap-forming member portion contacting the upper portion of the gel sheet device coincides with the upper edge face of the gel membrane, or the extent of overlapping of the gap-forming member portion upon the gel membrane is 5 mm or less.
