Abstract: A gel tray for a bacterial transformation lab exercise has a plastic body with four parallel gel channels and four filling ports, one for each channel into which unmodified bacteria and heat-shocked bacteria can be injected by students along with appropriate reaction constituents to demonstrate transformation of the bacteria under visualization. A seal may be provided to seal the tops of the gel channels and a lid can cover the gel tray during incubation.

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.

Abstract: The present invention discloses apparatuses and methods for the visualization of fluorophores in biological systems such as electrophoresis gels and cell cultures. Preferred embodiments of the apparatuses consists of a tray or tank having one or more light sources disposed to direct light through an electrophoresis gel disposed within the vessel such that the luminescence from fluorophores in the gel are easily visualized.

Abstract: An electrophoresis running tank assembly includes a running tank and a power supply holder that is integral to the running tank. A lid is configured for covering the tank, with two activation arms depending downwardly from the lid and with peripheral vertical skirts of the lid overlapping the walls of the tank. Two switches are held by a switch assembly in the power supply holder and are accessible through a space between the power supply holder and a pin wall that supports two connector pins. When the lid is engaged with the tank, the activation arms extend into the space to abut and thereby close the switches, thereby electrically connecting the switches to the electrode. A power supply can be engaged with the pins to energize the electrodes.

Abstract: An electrophoresis running tank assembly includes a running tank and a power supply holder that is integral to the running tank. A lid with two pins protruding from it can be engaged with the running tank with the pins extending through holes in the power supply holder. A contact is positioned in each hole, and the contacts are electrically connected to an electrophoresis electrode in the running tank. When a power supply is advanced into the power supply holder and the lid is properly positioned on the running tank, the pins on the lid mate with receptacles of the power supply, thereby establishing a connection between the power supply receptacles and the contacts in the holes and, hence, the electrophoresis electrode.

Abstract: An electrophoresis gel package includes a unitary PVC housing including a cover joined to a holder by a living hinge. A tray that has gel disposed thereon is received into the holder, and the cover then moved to engage the holder and protectively enclose the gel. The housing includes structure which cooperates to limit unintended motion of the gel relative to the tray and to the housing.

Abstract: This invention provides a gel electrophoresis casting cassette for horizontal gel electrophoresis. The tray and lid of the cassette have locking means for securing the two parts to prevent damage to the slab gel and to create slab gels of uniform quality.
