Staining compositions and methods for use with a matrix, such as an electrophoretic gel, containing separated biopolymers. The compositions including an acid, an organic solvent, and a generally planar, fluid-permeable gel contact sheet consisting primarily of a non-cellulosic material. The acid and organic solvent may be sorbed to the fluid-permeable gel contact sheet, or may be sorbed to a layers contactable with a non-gel contact side of the gel contact sheet. In one embodiment, the composition is a source electrophoretic stain composition including a staining reagent. In one embodiment, the composition is a sink electrophoretic stain composition including a sorbent.

Kit for use in electrophoretic matrix staining

An electroblotting system including a cassette configured to receive a membrane and a material impregnated with at least one of proteins or nucleic acids. The cassette is connectable to a base such that a current is passable through the cassette to cause at least some of the proteins or nucleic acids to be transferred from the impregnated material to the membrane. The cassette has a first portion, a second portion configured to be releasably coupled to the first portion, and a coupling mechanism configured to releasably couple the first portion to the second portion. The cassette further includes an actuator operatively coupled to the coupling mechanism such that manual depression of the actuator causes the coupling mechanism to release the first portion relative to the second portion.
