A cassette (10) for use in the formation of an electrophoretic gel comprising two plates with substantially planar walls (11, 13) each having two sides and two ends so arranged in a side-by-side, spaced apart array to form a gel receiving space (15) between them, the improvement consisting of a plurality of projections (16) on one or each of the plates, the projections extending into the gel receiving space and the projections being so sized and so spaced apart over the surface of one or each of the plates that when a gel is introduced into the gel receiving space and a well-forming comb is inserted into the space, a plurality of spaced wells are formed in the gel, at least some of the wells being separated by a tongue of gel which surrounds and engages at least one of the projections, wherein the projections prevent the tongues of the gel from moving relative to the two plates when the electrophoretic gel is in use.
