ABSTRACT:
Gel holders for electrophoresis gels are made using fibers, particularly glass fibers, which are affixed to the substrates forming the gel holder using an adhesive. These gel holders can be made by placing a plurality of adhesive-coated fibers between a first planar substrate and a second planar substrate; and applying pressure to the outside of the substrates to adhere the fibers to the first and second substrates. This forms a gel chamber between the first and second substrates which has a thickness defined by diameter of the fibers. Alternatively, uncoated fibers may be laid down in pairs, with a line of adhesive disposed between each fiber of the pair. When the adhesive is cured, it binds the fibers in position as spacers. At the same time, the fibers isolate the adhesive from the gel compartment. In this way, interference of components of the adhesive with the polymerization of the a gel in the gel chamber can be avoided. Gel holders formed using either of these methods may be filled immediately with a gel forming solution such as a polyacrylamide, or they may be stored indefinitely and used as needed.
