Patent number: 7658827Abstract: Flat plates serving as molds and enclosures for slab gels are held together by a clamping frame in which the side edges of the plates slide into facing channels and are clamped by lever-operated cams that compress the channel walls against the plate surfaces. The joined plates are held on a vertical support rack containing a finger-operated spring-loaded notched clamp that presses down on the plates to seal the opening at the bottom edges of the plates against a gasket. A well-forming comb for insertion between the plates contains flexible outwardly angled fingers to seal against the spacers between the plates.Type: GrantFiled: June 22, 2006Date of Patent: February 9, 2010Assignee: Bio-Rad Laboratories, Inc.Inventors: Evelio Perez, George Fernwood

Patent number: 6558522Abstract: An electrophoresis apparatus for the simultaneous electrophoretic separation of a plurality of component mixtures using a disposable tray having a plurality of parallel troughs shaped to retain an elongate strip of isoelectric focusing medium and sufficient liquid to immerse the elongate strip. A frame is provided to retain the tray in a horizontal position using a pair of rotatably mounted support members moving between an open and closed position. Support members are also connected to a plurality of electrodes aligned with each of the troughs so that the electrodes are positioned clear of the troughs in the open position and positioned in the troughs when in the closed position.Type: GrantFiled: September 14, 2000Date of Patent: May 6, 2003Assignee: Macquarie Research Ltd.Inventors: Keith Leslie Williams, Mark Molloy, Andrew Arthur Gooley, Nicolle Hannah Packer, Ben Herbert, Bradley Walsh, George Fernwood, David Garfin

Patent number: 6451193Abstract: Electrophoresis is performed simultaneously in a multitude of slab gels in a single cell that supports the slab gels vertically and parallel to each other while immersed in a buffer solution, and that applies a voltage to all gels simultaneously through a single pair of plate electrodes. Temperature control is achieved by circulating the buffer solution upward through the cell, entering near the base of each slab gel and leaving near the top, and cooling the circulating buffer solution with a tube heat exchanger positioned on the floor of the cell.Type: GrantFiled: September 6, 2000Date of Patent: September 17, 2002Assignee: Bio-Rad Laboratories, Inc.Inventors: George Fernwood, Christina Whitman, Adriana J.

Patent number: 5164065Abstract: Sharkstooth combs for use in slab electrophoresis for holding samples above the gel prior to being separated in contiguous lanes are formed of a metallic core sheathed in a surface coating to render such a comb electrically insulating. The metallic core provides the comb with the strength needed to prevent breakage of the teeth, which is otherwise a problem due to the thinness of the comb.Type: GrantFiled: December 13, 1991Date of Patent: November 17, 1992Assignee: Bio-Rad Laboratories, Inc.Inventors: Gregory Bettencourt, George Fernwood, Efrem G. Hernandez, Lin Crawforth
