VERSATILE APPARATUS FOR POLYACRYLAMIDE AND AGAROSE-GEL ELECTROPHORESIS IN PLEXIGLAS SLAB GEL MOLDS

A simple vertical slab gel electrophoresis apparatus for analytical, preparative, and two-dimensional electrophoresis is described. The use of permanently sealed Plexiglas acrylic plastic slab gel molds which need to be sealed only at the bottom during gel formation, rather than the glass plate sandwich used in most previous designs, virtually eliminates leakage during gel formation and, in addition, permits the continuous monitoring with ultraviolet light of proteins and nucleic acids labeled with fluorescent dyes during electrophoresis. Results obtainable with this apparatus are equivalent to those achieved in other apparati which are more expensive to fabricate or purchase. © 1978.
