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;
at least one anode immersed in the anode reservoir and at least one cathode immersed in the cathode reservoir;
a first lens engaged with an opening of a housing supporting the tank, the first lens being elongated in a horizontal dimension, the first lens substantially filling the opening, plural first light emitting diodes (LED) arranged in a horizontal row along a first printed circuit board (PCB) comprising at least one connection to a power source to energize the first LEDs, the first PCB being mounted outboard of the first lens, the first LEDs being recessed radially outward of the inner surface and the first lens being located between the first PCB and a first side of the tank.

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.

9. 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 or gel tray containing gel; at least an anode reservoir and at least a cathode reservoir for holding buffer during electrophoresis of a substance in the gel; at least one anode immersed in the anode reservoir and at least one cathode immersed in the cathode reservoir; a first lens engaged with an opening of a housing supporting the tank, the first lens being elongated in a horizontal dimension, the first lens substantially filling the opening, plural first light emitting diodes (LED) arranged in a horizontal row along a first printed circuit board (PCB) comprising at least one connection to a power source to energize the first LEDs, the first PCB being mounted outboard of the first lens, the first LEDs being recessed radially outward of the inner surface and the first lens being located between the first PCB and a first side of the tank. - View Dependent Claims (10, 11, 12)

13. An assembly for electrophoresis, comprising:
-
at least one gel tray including gel; at least one support including a top surface configured for holding the at least one gel tray; at least an anode reservoir and at least a cathode reservoir for holding buffer during electrophoresis of the gel; at least one anode immersed in the anode reservoir and at least one cathode immersed in the cathode reservoir; at least one light source; the gel tray comprising a clear bottom wall defining a bottom surface, the bottom wall supporting the gel, the gel defining a top gel surface, the gel tray being positioned on the top surface of the support, light from the at least one light source propagating along a plane midway between the top surface of the gel and the bottom surface of the gel tray, wherein the top surface of the support is at least partially speculative and opaque such that a bottom of the gel tray in cooperation with the at least partially speculative and reflective top surface of the support promotes excitation of stain associated with a substance in the gel. - View Dependent Claims (14, 15, 16, 17, 18, 19)
