Abstract
Abstract Apparatus facilitating electrophoresis studies. A previously prepared gel is shipped and stored in a closed container with the gel and a moisture preserving pad disposed in space separated positions on the lid and bottom of said container. The container is separable for use with the gel carrying lid being used for the reception of specimens, antibodies, serums, etc. An electrophoresis cell is divided by a diaphragm element into separate receptacles that hold an electrolyte buffer solution with electrodes of a power source positioned in each receptacle. Movable support partitions that are selectively positionable in alternate slots have pocket elements to receive and hold moisture absorbing pads or wicks in close solution conducting contact with the supports to facilitate the wetting of the gel and to establish electrical contact therewith when the container is placed in inverted position on said supports. The electric charge of the power supply is transmitted to object study specimens in the gel. A cover encloses the cell and the contents thereof, and power is cut off to the apparatus when the cell cover is removed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
225 words
AppAratus useful in connection with electrophoresis studies comprising an upwardly opening cell structure having liquid-tight end and side walls, a liquid-tight intermediate wall for said cell structure dividing a lower portion of the cell structure into separate receptacles adapted to receive an electrolytebuffer solution, separate electrodes in each of said receptacles in position for contact with said buffer solution, support partitions that are of operative height greater than the height for said intermediate wall for disposition in each of said receptacles, a carrier structure having a specimen receiving surface on a lower or inverted face of said carrier disposed for support by and extension between the support partitions in the separate receptacles, said specimen receiving surface accordingly being disposed across and above said intermediate wall, said carrier structure further having edge elements extending downwardly at all sides of said specimen receiving surface for the protection of said specimen receiving surface and said support partitions providing slots for the accommodation of said downwardly extending edge elements, wick elements of a type to be wetted by the buffer solution on each of said support partitions and in wetted contact with the buffer solution and the specimen receiving surface of said carrier whereby electrical current may be delivered to the specimen receiving surface, and a power source for selective connection to said electrodes to provide said electric current.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
57 words
The apparatus as set forth in claim 1 and further comprising a cover for enclosing all of said upwardly opening cell structures and the contents thereof, and an extension on said cover interposed intermediate said power source and electrodes whereby the power source is disconnected and power to said apparatus is interrupted when the cover is removed.
Claim 4
Dependent Claim
42 words
The apparatus as set forth in claim 2 wherein said cover engages the end and side walls of said cell structure and said extension is positioned along one of said walls with said extension providing an opening through which the electrodes extend.
Claim 5
Dependent Claim
49 words
The apparatus as set forth in claim 3 wherein said electrodes are surrounded by the opening in said cover extension and wherein power is provided by an electrical outlet plug adapted for selective interconnection to said electrodes and of size greater than the size of said cover extension opening.
Claim 6
Dependent Claim
35 words
The apparatus as set forth in claim 1 wherein the walls of said cell structure provide multiple sockets for the selective reception of said support partitions whereby carrier structures of varied size may be utilized.
Claim 7
Dependent Claim
61 words
The apparatus as set forth in claim 1 and further comprising pockets on said support partitions at positions beneath the level for buffer solution, said pockets being adapted to receive said wick elements for holding the wicks in close contact with said support partitions whereby an additional capillary action is established for the delivery of additional solution to the specimen surface.
Claim 8
Dependent Claim
42 words
The apparatus as set forth in claim 1 wherein the carrier structure inclusive of the depending edge elements is the lid component of a container and further comprising a bottom for selective specimen preserving mating and enclosing engagement with said carrier lid.
Claim 9
Dependent Claim
37 words
The apparatus as set forth in claim 7 and further comprising separable hinge and fastener components for said container whereby the carrier lid alone can be used in said cell structure as the specimen supporting carrier structure.
Claim 10
Dependent Claim
29 words
The apparatus as set forth in claim 8 and further comprising a gel solution applied to the specimen surface of said carrier lid for contact with said wick elements.
