ABSTRACT:
An electrophoresis gel sheet is composed of electrically non-conductive organic polymer films, gel-casing spacers having predetermined thicknesses and disposed at both side edge portions between the two polymer films, and an electrophoresis medium of uniform thickness encapsulated between the two polymer films at the zone between the gel-casing spacers. A gap-forming spacer is secured to an outer surface of at least one of the polymer films constituting the electrophoresis gel sheet so that, when the electrophoresis gel sheet is inserted between electrically non-conductive supporting plates before electrophoresis, a gap is formed by the gap-forming spacer between a surface of the sheet supporting plate and the surface of the electrophoresis gel sheet which stand facing each other, whereby the surface of the sheet supporting plate and the surface of the electrophoresis gel sheet which stand facing each other are prevented from closely contacting each other, and the electrophoresis medium is prevented from being distorted by dust or the like.
