An apparatus for staining and destaining one or more slab gels subsequent to electrophoresis comprises a liquid impermeable enclosure having a bottom, a sidewall portion attached to the bottom and a removable top. A plurality of channels are formed in the sidewall portion of the container. At least one and preferably a plurality of cassettes are provided for retaining the slab gels. The cassettes are disposed within the channels. Each cassette comprises a pair of plates that are hinged together at one end and have a lock at the other end to secure the plates together. Each of the plates has a recess therein and a fluid permeable mesh covers each recess to form a slab gel retaining chamber therebetween. Depending upon the fluid used in the container, the slab gels can either be stained or destained. An advantage of the present apparatus is that the slab gels can be removed from the container without having to pour-off the staining or destaining solutions, thus achieving economy of material usage. Additionally, the cassettes protect the slab gels from damage since the slab gels are loosely retained therein and can be transferred from a staining container to a destaining container merely by transferring the cassettes containing the slab gel.
