Abstract

Abstract An electrophoresis kit and system is provided wherein a base unit containing the electrodes and spaced apart buffer chambers and the test samples are contained in the bridges in a corresponding lid in contact with the buffer chambers. The test samples are poured into molding bridge chambers in the base unit, the lid placed thereon, transferring the test sample to the lid, and the lid replaced to make electrical contact with the spaced bridge chambers in the base. Registration means are provided for correctly positioning the lid with respect to the base for operation of the electrophoresis apparatus. The kit may assume a variety of shapes, such as rectangular or circular, and the entire assembly is preferably made of molded consumable plastic material so as to be disposable. The invention includes the method of assembly and operation of the electrophoresis unit.
