Abstract: An apparatus for preparation of an electrophoresis slab gel may include a base having an opening configured to receive a cassette configured to contain an electrophoresis slab gel, a clamping mechanism configured to move relative to the base between an open position in which the clamping mechanism permits insertion of a cassette into the base, and a closed position in which the clamping mechanism is configured to clamp a cassette received in the base, a compressible pad operatively coupled to the clamping mechanism in a position to compress against a cassette received in the base in the closed position of the clamping mechanism. The cassette may include a first plate and a second plate, and a spacer mechanism separate from each of the first and second plates, the spacer mechanism configured to be positioned between the inner faces of the first plate and the second plate.

Abstract: The present invention provides methods and compositions for labeling, separating and analyzing proteins, particularly a specific protein of interest within a cell lysate or in a mixture of proteins. The proteins are labeled with an amine reactive or thiol reactive fluorescent dye, or an amine reactive fluorogenic reagent that becomes fluorescent upon reacting to amine groups located on the protein. Following the labeling step, the proteins within the mixture can be separated and analyzed. In a further embodiment, a tag binding fluorogenic reagent that can bind to a tag on a tagged protein is added to specifically label the protein of interest.
