Abstract: Electrophoresis system comprising at least one type of electrophoresis gel card, at least one type of blot membrane card, an electrophoresis apparatus for running electrophoresis experiments using the electrophoretic gel card, a blot transfer unit for transfer of separated sample from the electrophoresis gel card to the blot membrane card, an imaging apparatus for recording images of separated sample in the electrophoresis gel card and the blot membrane card, wherein; the electrophoresis gel card and the blot membrane card each comprises a rigid support provided with an alignment structure defining a positional reference for mutual alignment during transfer, and for alignment with respect to a complementary alignment structure in the imaging apparatus to provide mechanically aligned images of separated sample in the electrophoresis gel card and the blot membrane card.

Abstract: Method of manufacturing an electrophoresis gel cassette with a cassette housing defining a gel compartment for molding a gel member,comprising the steps of: molding in a rigid material a cassette housing member with an external face, an internal face defining at least a section of the gel compartment, and at least one opening for providing access to the gel compartment from the external face, and molding a closing member formed to close the at least one opening of the cassette housing member at the external face, wherein the closing member is molded with the cassette housing member acting partly as mold, and is comprised of an elastic material with non-permanent adhesion to the rigid material to make the closing member selectively removable.
