ABSTRACT:
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.
