APPARATUS FOR ELECTROPHORESIS

摘要

An apparatus for electrophoresis comprises a base incorporating an integral or separable tray defining a plurality of parallel troughs into which IPG strips may be placed is disclosed. The apparatus further includes a lid. The lid has a top and depending sides and is configured to fit over the base. The lid defines at least one opposed pair of depending electrodes, and also, spaced inwardly of the electrodes relative to the sides of the lid, a pair of opposed depending members for applying pressure to IPG strips located in use, in troughs of the tray. In a variant the lid provides individually addressable electrodes for each of the grooves in the tray wherein the lower edge of the depending electrode bars and the IPG holder bars are all crenellated. In this manner, the lid of the cassette provides an individual pair of opposed electrodes for each of the IPGs running in the tray, and the voltage between each of the pairs of electrodes can be controlled independently of the voltage between other opposed electrode pairs.
