PCT No. PCT/CA96/00832 Sec. 371 Date Dec. 31, 1998 Sec. 102(e) Date Dec. 31, 1998 PCT Filed Dec. 12, 1996 PCT Pub. No. WO97/21995 PCT Pub. Date Jun. 19, 1997Gel holders for electrophoresis gels are made using clad fibers, particularly glass fibers as spacers between substrates. A plurality of fibers with a high-melting interior core and a low-melting external cladding are placed between a first planar substrate and a second planar substrate. The fibers are heated to a temperature sufficient to at least soften the exterior cladding of the fibers without softening the interior core of the fibers, and then cooled while they are in contact with the first and second substrates to solidify the exterior cladding. This adheres the fibers to the first and second substrates, and forms a gel chamber between said first and second substrates. The gel chamber has a thickness defined by interior core of the fibers. The fibers may be heated before or after the second substrate is placed over the top of the fibers. The gel holders thus formed may be filled immediately with a gel forming solution such as a polyacrylamide, or they may be stored indefinitely and used as needed.
