Foto/phoresis apparatus
First Claim
1. An apparatus for separating and identifying DNA fragments in agarose gels comprisinga tray having a front wall and a back wall,gate means mounted on each side of the tray for defining an enclosure within said walls for the agarose gel,means positioned in said tray for defining wells in the agarose gel for DNA fragments,an electrophoresis chamber having a platform and a buffer well on each side of the platform, said gate means being movable to positively locate the tray on said platform,means in said chamber for establishing an electric field across said tray,and means for illuminating said tray to visually observe the migration of said DNA fragments in the agarose gel.

Abstract
An apparatus for electrophoretically separating, visualizing and photographing DNA fragments in agarose gels, the apparatus including an electrophoresis chamber havng a platform and an electrode located on each side of the platform, a transilluminator having a UV light source, a frame defining a viewing opening over said light source, and a UV filtering cover for enclosing said viewing opening, a tray having movable gates for defining an enclosure for the agarose gel in one position and for locating the tray on the platform in the chamber in the other position, and a camera assembly adapted to be mounted on the frame in the transilluminator for providing 1:1 magnification photographs of the DNA fragment migration patterns.

5. The combination of an electrophoretic chamber, a transilluminator and a tray for holding agarose gel containing DNA fragments,
said chamber including a platform for supporting said tray and a well on each side of said platform for a buffer, said tray including means for forming an enclosure for said gel in one position and for positively locating the tray on the platform in the other position, means in said chamber for establishing an electrical field across said tray to effect a migration of said DNA fragments into the agarose gel, and said transilluminator including means for defining a viewing opening for illuminating said tray on said transilluminator.

9. The combination of an electrophoretic chamber, a transilluminator and a tray for holding agarose gel containing DNA fragments,
said chamber including a platform for supporting said tray and a well on each side of said platform for a buffer, said tray including a front wall, a back wall and a gate on each side, said gates being movables between a first position for forming an enclosure for said gel, and a second position for positively locating the tray on the platform in said chamber, means in said chamber for establishing an electrical field across said tray to effect a migration of said DNA fragments into the agarose gel, and said transilluminator including a UV light source and a frame having an inner peripheral surface for defining a viewing opening for positively locating said tray over said light source in said transilluminator, and an outer peripheral surface.
-
13. A transilluminator for viewing a tray containing DNA fragment migration patterns in agarose gel, said transilluminator comprising
a housing for a UV light source, and a cover formed of a UV filter material mounted on said housing in a position to cover said light source whereby a tray positioned over said light source can be viewed through said cover without protective glasses.
-
17. The combination of an electrophoretic chamber and a tray for holding an agarose gel containing DNA fragments, said chamber having a platform for supporting said tray, a buffer well on each side of said platform and means for establishing an electric field across said platform,
said tray including means for centering said tray on said platform.
