Abstract: This invention is directed to a cassette for electrophoresis gels comprising: first and second planar wall members having inner and outer surfaces, top and bottom edges, and lateral edges wherein the wall members are oriented generally parallel to each other and such that the inner wall of each wall member is proximate to the inner wall of the other wall member; spacing means disposed between the inner walls of the wall members and adapted to provide a space for an electrophoresis gel between the inner walls of the wall members, wherein the cassette has an interior which is defined by the space between the wall members; and locking means adapted to prevent locking engagement of the members unless the inner surfaces of the wall members and are substantially parallel to each other and are separated by a predetermined distance, and when the wall members are in locked engagement, to substantially prevent any movement of the wall members away from such locked engagement.

Abstract: An improved cassette for use in the formation of an electrophoretic gel comprises two plates with substantially planar walls having two sides and two ends so arranged in a side by side spaced apart array to form a gel receiving space between them. A plurality of dividing ribs on one or each of the walls extend from a first end of the wall or walls substantially parallel to at least one of the sides thereof to a rib base end. The ribs extend into the space so as to subdivide at least one end of the space into a plurality of substantially parallel wells. A plurality of holes extend through at least one of the walls of the cassette located at or adjacent the base of the dividing rib and aligned with the rib. The arrangement of holes allow sufficient current flow to replace that lost due to the dividing ribs.

The structure retains the advantage of having solid dividing walls which are considerably more resilient than dividing walls made from fingers of gel even when reinforced with pegs or projections.
