Apparatus is disclosed for carrying out a moving wall type electrophoresis process for separation of cellular particles. The Apparatus includes a water-tight housing (10) containing an electrolytic buffer solution. A separation chamber (12) in the housing is defined by spaced opposed moving walls (14 and 16) and spaced opposed side walls (18 and 20). Substrate assemblies (26 and 32), which support the moving wall include vacuum ports (60) for positively sealing the moving walls against the substrate walls. A plurality of suction conduits (62) communicate with the suction ports and are arranged in the form of valleys in a grid plate (64). Raised land portion of the grid plate support the substrate walls against deformation inwardly under suction. Cooling chamber (70) carried on the back side of plate (64). The apparatus also has tensioner means including roller (80) and adjustment screws (82) for maintaining the belts in position and a drive arrangement including an electric motor (90) with a gear (94) affixed to its output shaft. Electrode assemblies (56 and 57) are disposed to provide the required electric field.
Electrophoresis apparatus for separating colloidal and macromolecular cellular particles of the type having a separation chamber in which said particles are separated into at least one fraction band of a cellular species, sample insertion means for inserting a sample stream containing said particles into a buffer solution in said separation chamber and electrode assemblies creating an electrical field in said separation chamber whereby said cells separate into said fraction bands;
Electrophoresis apparatus for separating cellular particles into at least one fraction band by means of inserting a sample stream of said particles into a buffer solution and impressing an electrical field in said buffer solution whereby the cells separate into said fraction band, said apparatus comprising:
