A precast slab gel for use in submerged ("submarine") horizontal electrophoresis is formed in a tray that includes a flat base and two raised walls on opposing sides of the base, the walls containing one or more tabs on their outer surfaces, the tabs mating with grooves in the interior walls of the tank. The mating of the tabs with the grooves prevents movement and floating of the tray within to the electrophoresis cell during use. The tabs are designed to mate with grooves that are present in the tank for other purposes, which adds to the versatility of the design. Further versatility is achieved by joining the tabs to the tray walls by thin webs, which make the tabs readily removable, thereby rendering the tray usable in cell tanks that do not contain grooves. Further aspects of the invention include pins or posts extending upward from the tray base to anchor the gel, and the printing of indicia on the tray base by hot foil stamping, with the discovery that indicia printed in this manner are capable of producing a fluorescent image as part of the image produced by fluorescent-dyed protein spots in the electropherogram.
