Abstract
An electrophoresis gel has a colored or pigmented loading area at one edge having a plurality of sample wells for receiving samples, the loading area extending beyond the ends of the wells so that the wells can be visually differentiated from the surrounding colored material in the loading area. The remainder of the gel is transparent or substantially transparent.
Claims12
An electrophoresis gel, comprising:
- a slab of electrophoresis gel material having opposite edges;
- a sample loading portion extending from one edge of the slab having a plurality of empty sample wells for receiving samples and a gel-containing area surrounding the sample wells;
- a resolving portion extending from the sample loading portion to the opposite edge of the slab and including a gel material;
- and
- the gel-containing area surrounding the sample wells comprising gel material containing insoluble pigmented material, whereby the entire gel-containing area of the sample loading portion contains insoluble pigmented material and is visually differentiated from the sample wells before samples are loaded into the wells, and the gel material in the resolving portion containing no insoluble pigmented material.

An electrophoresis gel assembly, comprising:
- a gel holding cassette;
- and
- a gel in the cassette having a surface, a sample loading portion extending from the surface to a first edge spaced from the surface and a resolving portion extending from the sample loading portion and including a gel material, the loading portion of the gel comprising a plurality of empty sample wells extending from the surface of the gel, and a colored area surrounding the sample wells containing a gel material colored with an insoluble pigmented material and the gel material of the resolving portion containing no insoluble pigmented material;
- whereby the colored area of the sample loading portion is visually differentiated from the empty sample wells prior to loading of samples into the wells.
