Abstract: The procedures involved in isoelectric focusing that entail the use of an electric current can be performed with the gel side of the IPG strip facing either up or down in a tray and electrode assembly in which the electrodes are mounted on an insert from which the inner ends of the electrodes extend into the troughs to reside either below the IPG strips or above them. Slots in one part (either the insert or the tray) mate with walls or partitions in the other part to secure the two parts together, and the heights of the electrodes within the troughs of the tray can be adjusted by the height of the insert in the tray or by a resilient mounting of the electrode to the insert.

Abstract: A slab gel cassette is formed from generally flat plates welded together along their borders with a gel space between the plates that is open at the top and bottom edges of the plates to expose the opposing ends of a gel in the gel space to buffer solutions in which electrodes are immersed. The plates are shaped such that the weld line does not intersect with the bottom opening of the gel space. Sealing of the bottom of the gel space, which is necessary for gel casting, is achieved by placing a seal-ing strip over the bottom opening with no danger of leakage of the gel solution along a weld line.
