Slab gel cassettes with side openings

摘要

A slab gel cassette for slab electrophoresis with a side opening or slot for the bottom edge of the gel is improved by directing the foot of the gel space (i.e., the lower edge of the space that turns toward the side opening) at an obtuse angle (greater than 120 DEG ) relative to the remainder of the slab rather than the 90 DEG angle of the prior art. The gel can be flattened for drying without cutting off the foot. A further improvement is the placement of notches in the side edges of the cassette opposite the ends of the slot, and a still further improvement is the placement of additional notches in the ends of the slot itself opposite the aforementioned notches.
