Electrophoresis plate

An improved electrophoresis plate of the type which includes a substrate and an electrophoresis medium layer on the substrate and which is packaged with a removable film on the electrophoresis medium layer, the electrophoresis medium layer including a liquid and a gel in which the liquid is retained, removal of the film from the electrophoresis medium layer leaving liquid which has been expressed from the gel on the electrophoresis medium layer, wherein the improvement comprises:

• the electrophoresis medium layer comprising agarose as a gelling agent;
• wetting means in the electrophoresis medium layer for causing the liquid expressed from the electrophoresis medium layer to form a substantially uniform layer on the electrophoresis medium layer;
• and
• a removable film on the electrophoresis medium layer.

A method of making an electrophoresis gel plate package comprising the steps of:

• providing a container having first and second portions;
• providing an electrophoresis medium layer within said container first and second portions, said electrophoresis medium layer including a liquid and a gel in which the liquid is retained;
• providing a wetting means in the electrophoresis medium layer in an amount effective for causing the liquid expressed from the electrophoresis medium layer to form a substantially uniform layer on said electrophoresis medium layer;
• and
• providing a removable film on the electrophoresis medium to retain the expressed liquid from the electrophoresis medium prior to electrophoresis.

An electrophoresis gel plate package comprising:

• a container having first and second portions;
• an electrophoresis medium layer positioned within said container portions, said electrophoresis medium layer including a liquid and a gel in which the liquid is retained;
• wetting means in the electrophoresis medium layer in an amount effective for causing the liquid expressed from the electrophoresis medium layer to form a substantially uniform layer on said electrophoresis medium layer;
• and
• a removable film on the electrophoresis medium layer.
