1. Assembly for electrophoresis, comprising:
- at least one tank formed with a gel tray platform including a top surface configured for holding at least one gel tray containing gel;
at least an anode reservoir on a first side of the gel tray platform and at least a cathode reservoir on a second side of the gel tray platform, both reservoirs configured for holding buffer during electrophoresis, the anode reservoir being larger than the cathode reservoir, both reservoirs having a respective closed bottom, a respective top opposed to the respective closed bottom, and a respective buffer chamber therebetween, the anode reservoir and the cathode reservoir extending laterally inward under the gel tray;
at least an anode in the anode reservoir and at least a cathode in the cathode reservoir, the anode and cathode being disposed in the respective buffer chamber and spaced above the respective closed bottom, a first distance being established between the anode and a side of the gel tray facing the anode and at least a second distance being established between the cathode and a side of the gel tray facing the cathode, the first distance being greater than the second distance;
at least a first source of illumination facing the platform;
at least a second source of illumination facing the platform and facing the first source of illumination with the platform between the first and second sources of illumination, the first and second sources of illumination positioned to emit light along respective first and second central light axes that are coplanar with each other and that are parallel to and spaced from the top surface of the gel tray platform, the top of the gel tray platform being a horizontal top on top of which is located a shelf platform with a top surface that is at least partially speculative and opaque and configured for receiving the gel tray thereon.

Abstract
An electrophoresis running tank assembly uses two opposed rows of LEDs to illuminate DNA-containing gel on a transparent tray positioned between the rows. A respective cylindrical lens is positioned horizontally between each row and a respective edge of the tray. The optical axis of the illumination light is midway between a bottom surface of the gel tray and a top surface of the gel.
