Patent number: 7825227Abstract: The present invention provides a method for purifying a protein complex and the components comprising the complex from a cell, a cell or tissue lysate or a whole organism by employing a combined set of affinity tags of high affinity, specificity and ease of elution. The method involves using a protein or a peptide modified to contain one or more affinity tags separated by one or more specific protease cleavage sites to isolate any interacting proteins or fragments thereof. Specifically exemplified is a method employing a modified bait containing AviTag or GST and a removal tag of His6 hexapeptide positioned proximal to the bait such that any excess bait can be efficiently removed from the purified complex yielding enriched interacting proteins prior to subjecting the complex for further identification of individual components. The identification of the proteins or fragments thereof contained in the protein complex will provide new targets for the identification of new pharmaceuticals and diagnostic tools.Type: GrantFiled: November 9, 2004Date of Patent: November 2, 2010Assignee: Prolexys Pharmaceuticals, Inc.Inventors: John J.

Patent number: 6479020Abstract: An improved multi-well synthesis and filtration apparatus (10) includes a deep-well synthesis block (12) having a plurality of flowthrough wells (24) optionally fitted with filter disks (48) each of the wells (24) being integrally formed in the synthesis block (12), such that any material placed in the wells (24) is in immediate contact with the material of the synthesis block (12), an upper cover (14), a lower cover (16), and a pair of first and second sheet gaskets (18, 20). The first and second sheet gaskets (18, 20) are interposed between the upper and lower covers (14, 16) to seal inlet portions (38) and outlet spouts (40) of the wells (24). The upper and lower covers (14, 16) are independently releasable, and, with the gaskets (18, 20) form a gas tight seal, so that material is retained in the wells (24) when the lower cover (16) is removed, but the upper seal maintained.Type: GrantFiled: February 4, 2000Date of Patent: November 12, 2002Assignee: Robbins Scientific CorporationInventors: James E.

Patent number: 6054100Abstract: A multi-well synthesis and filtration apparatus (10) dimensionally arrayed in a standard multi-well format for performing multiple chemical reactions includes a deep-well synthesis block (12) with flowthrough wells (24) fitted with filter disks (48), an upper cover (14), and a lower cover (16). First and second sheet gaskets (18 and 20) seal inlet portions (38) and outlet spouts (40) of the wells (24). An optional skirt (26) provides a site for the independently releasable attachment of the upper and lower covers (14 and 16) to the block (12) while maintaining the seal on the unreleased cover. An alternative synthesis apparatus (310) additionally includes a reinforcement assembly (372) to improve the clamping action of the covers (14 and 16) upon the synthesis block (12). A rotating carrier apparatus (200) and a modified oven assembly (202) are provided to enable agitation and heating of multiple synthesis blocks (12) simultaneously.Type: GrantFiled: November 18, 1997Date of Patent: April 25, 2000Assignee: Robbins Scientific CorporationInventors: James E.

Patent number: 5916526Abstract: A multi-well container (10) is provided in which a greater number of wells may exist than heretofore possible while still maintaining a standard multi-well plate tube array format and footprint. The multi-well container (10) is comprised of a rectangular array of tubes (12) in standard tube format held together by an integrally fashioned plate portion (16). The tubes (12) are subdivided by partitions or septa (14) which extend the height of the tubes (12). Each septum (14) may constitute a single wall or may be comprised of any number of fins (32) which are integral with internal tube surfaces (28). In a symmetrical design with four such fins (32), the fins (32) radiate at angular intervals of 90 degrees from a common central axis (34) with which all four fins (32) are integral. Thus, the septa (14) serve to compartmentalize each tube (12) into symmetrical quadrants of four smaller wells or sub-tubes (30).Type: GrantFiled: November 3, 1997Date of Patent: June 29, 1999Assignee: Robbins Scientific CorporationInventor: Paul B.

Patent number: 4755356Abstract: A locking microcentrifuge tube (10) is provided which is capable of being sealed in either of two manners, one being a friction-fit seal which is easily opened and the other being a "locked" seal for higher stress applications. The tube body (12) is adapted to mate with the cap (14) at an aperture (24) such that the plug portion (36) of the cap (14) and the aperture (24) form the friction-fit seal at the early stages of insertion. A collar (26) is provided about the aperture (24) on the tube body (12). The collar (26) is formed to include one or more circumferential projections (28, 30). The cap (14) is formed to include depressions (32, 34) adapted to mate with the projections (28, 30) upon full insertion of the plug portion (36) to create the "locked" seal. The cap (14) is secured to the tube body (12) by a hinge (38) and a tab (40). The primary usage of the locking microcentrifuge tube (10) is in biomedical laboratory analysis.Type: GrantFiled: January 23, 1986Date of Patent: July 5, 1988Assignee: Robbins Scientific CorporationInventors: Paul B. Robbins, Arthur J. Robbins, Thomas R. Sutton

Patent number: 4390111Abstract: The present invention is an improved sealable vial for storage of materials. The vial includes a tubular body portion sealed at one end and provided with an aperture at the opposite end. The tubular body is further provided with a male spiral thread about the aperture end and a tapered section extending inward from the aperture. A sealing insert is attached to the body for positioning in either a closed position wherein it seals the aperture or an open position wherein the aperture is open. A cap fits over the sealing insert in the closed position and seals the vial. The cap includes female threads which mate with the male threads of the tubular body to secure the closure.The vial is particularly adapted for cryogenic storage of organic samples. The vial is also adaptable to other applications wherein complete sealing is required under wide temperature and pressure range conditions.Type: GrantFiled: February 8, 1982Date of Patent: June 28, 1983Assignee: Robbins Scientific CorporationInventors: Arthur J. Robbins, Paul B. Robbins, Dennis C. Thompson
