Abstract
Slab gels in parallel plate gel enclosures are readily placed in an electrophoresis cell where they are in full contact with upper and lower electrode buffers and reliably sealed against leakage with relatively few manual manipulations. The gel enclosures are pressed against an inner frame to form an upper buffer chamber, and the inner frame is inserted in an outer clamping frame in which the pressure between the gel enclosures and the inner frame is maintained by a cam-operated pressure plate. The clamping frame is then placed in a tank serving as the lower buffer chamber.
Claims10
Apparatus for securing a parallel plate gel enclosure to a frame to form a liquid-retaining chamber for an electrophoresis buffer, said apparatus comprising:
- a gasket between said frame and said gel enclosure;
- a housing;
- a pressure plate movably received inside said housing, said pressure plate defining a cavity within said housing to receive said gel enclosure and frame;
- a pair of cams rotatably mounted to said housing in engagement with said pressure plate;
- and
- means for rotating said cams to urge said pressure plate toward said cavity, such that when said gel enclosure, gasket and frame are received in said cavity, said gel enclosure is pressed against said gasket and frame to form a fluid-tight seal.
