ABSTRACT:
An electrophoresis plate of the type including a base layer of an electrophoretic medium containing some buffer material and a method of making such an electrophoresis plate. On the base layer of the plate there are formed buffer blocks made up of an electrophoretic medium having a lower electroendosmotic potential than that of the base layer. The buffer blocks contain buffer material for functioning as a self-contained reservoir during electrophoresis. The method of the present invention includes continuous casting of the buffer blocks and also includes casting the buffer blocks as a sequence of discrete layers.
