Claim:
1. A gel and membrane combination unit device for electrophoretic separation and transfer of biomolecules to a blotting membrane, comprising: a first gel matrix supporting plate having at least one region made from an opaque semi-conductive polymer; a second gel matrix supporting plate substantially parallel to the first gel matrix supporting plate, the second gel matrix supporting plate having at least one region made from an opaque semi-conductive polymer; a gel matrix between the first and second gel matrix supporting plates, wherein the gel matrix is capable of separating biomolecules such as proteins by size within the gel matrix when an electric current flows between electrodes of opposite polarity on opposing sides of the gel matrix; and, a blotting membrane between the gel matrix and at least one of the first and second gel matrix supporting plate, wherein the blotting membrane is capable of immobilizing biomolecules such as proteins transferred from the gel matrix after separation without physically transferring the gel matrix to the blotting membrane.
