Gel plugs that can be stored in a sealed condition and delivered individually to an electrophoresis gel as standards for electrophoretic separations are retained in a cartridge that is cleanly breakable into individual sections, each section retaining a gel plug of predefined dimensions with standard solute mixtures embedded in the plug. The separation of any single section from the cartridge exposes opposing edges of the gel plug which permits the user to insert an implement into the section interior and to urge the plug out of the section and into a well of an electrophoresis gel. All manipulations are performed without any need for contact between the user and the gel.
A gel plug cartridge for use as a source of standards in gel electrophoresis, said gel plug cartridge comprising a plurality of sections that are manually separable along predetermined separation lines, an internal cavity extending through all sections and filled with a gel in which is embedded a preselected mixture of solutes to be used as a standard, and, for any single section once separated from said cartridge, means for urging gel from said section out of said section and into a well of a slab gel.
