A system for electrophoretic analysis includes four tanks, each of which carries an electrolytic solution which accesses a different edge surface of a pair of parallel gel plates. The gel plates include an electrophoretic separation path formed of a selected medium, e.g. an isoelectric focusing gel, extending in a space between the plates and across opposite edges of the plates. A pair of nonpolar barrier webs extend between the plates parallel to and on each side of the path. A different medium, e.g. a running gel, occupies the areas between the gel plates from the opposite sides of the barriers to the remaining edges of the plates. A pair of gaskets are positioned along plate edges which are perpendicular to the path. The gaskets include access apertures for the path and the barriers. A specimen is positioned within a channel leading from an electrolytic solution tank to the path aperture of a gasket and between a dam and the aperture. Electrophoretic separation of the specimen constituents within the separation path is achieved by current flow between a pair of tanks which communicate with the path through the gasket apertures. The barriers are removed preferably by aspiration after specimen separation. An equilibrating medium and gel are infused into the spaces previously occupied by the barriers and electrophoretic separation into the different medium is commenced by current flow between the remaining tanks which access the edges of the gel plates in communication with the different medium.

DETAILED DESCRIPTION Having thus described the invention, there is claimed as new and desired to be secured by Letters Patent: 1.
An apparatus for conducting electrophoretic analysis, the apparatus comprising means for supporting an electrophoresis gel slab, the gel slab including a separation path comprising a first gel and defined by the space between a pair of parallel gel plates and a pair of barrier webs, the gel slab further including a second gel positioned in the space between the gel plates and adjacent at least one barrier web, the apparatus further comprising means forming a first pair of tanks for carrying an electrolytic solution and electrode means communicating with the electrolytic solution in each tank, means accessing the solution of each tank to opposite ends of the separation path, means for accessing the barrier webs for aspiration of the barrier webs from the gel slab after electrophoretic separation of a specimen in the separation path, the accessing means including means for permitting the infusion of an equilibrating medium into the spaces between the gel plates previously occupied by the barrier webs, the apparatus further including a second pair of tanks for carrying an electrolytic solution and electrode means communicating with the solution in each of the tanks of the second pair, means for accessing the solution of each tank of the second pair with the second gel, the specimen particles separated in the separation path being further separated by particle size in the second gel when an electrical potential is applied between the solutions in each of the tanks of the second pair, whereby two dimensional electrophoretic analysis is obtained without the necessity of manipulating the gel of the separation path.
2.
An apparatus for conducting electrophoretic analysis constructed in accordance with claim 1 wherein the means for supporting the gel slab includes a generally flat planar platen and a pair of parallel side walls, the means for accessing the barrier webs including means forming slots in the side wall in registry with the barrier webs whereby a syringe may be placed within the slots for aspirating the barrier webs
