Abstract
Isoelectric focusing gels are cast in a rod-shaped casting mold split longitudinally into two halves, each half having a half-circle profile so that the combined halves form a completed mold that is tubular in shape with a circular cross section. Flat grooves are cut into the flat contacting surfaces of each of the mold halves, the grooves in direct opposition to one another to form a chamber of rectangular cross section extending the full length of the mold and open at both ends. One groove receives a flexible backing strip for the gel and the other serves as the casting chamber for the gel. Once the gel is cast in this mold, isoelectric focusing can be performed as if the gel were a tube gel, and the two mold halves are then readily separated to permit removal of the gel and its transfer if desired to a second dimension separation.
