Abstract
A bufferless electrophoresis system for separation of DNA or the like includes a disposable cassette comprising a housing having open ends, a three dimensional gel body in the housing for defining a path, a sample well in a top surface of the gel for introducing a sample into the path at one end thereof, an electrically conductive film closing the ends of the housing and contacting the ends of the gel, and an electrical circuit for selectively applying an electrical potential via the electrically conductive film to the ends of the gel. A holder having spaced apart opposed terminals may be used to hold the cassette and apply the electrical circuit to the cassette.
