Abstract
Abstract An electrophoretic gel container for protecting an electrophoresis plate during shipment and storage, the electrophoresis plate being the type including a substrate having a major surface and a gel layer adhered to a portion of the major surface with the substrate including a peripheral portion free of the gel layer. The container includes a top portion and a bottom portion which are sealingly engageable with one another. The top and bottom portions have cooperating projections such that the top and bottom may be interlocked together. The gel layer substrate includes alignment apertures and the container includes alignment sockets in the bottom portion and locking pins in the top portion. The alignment sockets extend through the alignment apertures in the electrophoresis plate and the locking pins engage the alignment sockets to further secure the electrophoresis plate against movement. The container top portion is provided with stacking posts to support and distribute weight when a plurality of containers are stacked vertically.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
119 words
A container for protecting and enclosing an electrophoresis plate, the electrophoresis plate including a substrate having a generally flat surface and a gel layer adhered to a portion of the generally flat surface of the substrate, the substrate including a periphery which is free of the gel layer, said substrate periphery including alignment means, the container comprising: a top portion and a bottom portion which when closed are sealingly engageable with one another; the bottom portion having a cavity for receiving an electrophoresis plate; and means for securing the top portion and bottom portion together and for preventing movement of an electrophoresis plate received in said cavity, said securing means extending through the alignment means of the electrophoresis plate.
Claim 2
Dependent Claim
119 words
A container for protecting and enclosing an electrophoresis plate, the electrophoresis plate including a substrate having a generally flat surface and a gel layer adhered to a portion of the generally flat surface of the substrate, the substrate including a periphery which is free of the gel layer, said substrate periphery including alignment means, the container comprising: a top portion and a bottom portion which when closed are sealingly engageable with one another; the bottom portion having a cavity for receiving an electrophoresis plate; and means for securing the top portion and bottom portion together and for preventing movement of an electrophoresis plate received in said cavity, said securing means extending through the alignment means of the electrophoresis plate.
