Patent number: 7951610Abstract: A reaction method of performing an adsorption reaction in which a subject substance of analysis is specifically adsorbed in a first channel, the method includes: flowing a specimen liquid to a second channel connected to the first channel so that the specimen liquid is fed to the first channel, the specimen liquid containing the subject substance and a labeled substance that can be bonded to the subject substance; stopping feeding of the specimen liquid by detecting an event that a rear end of the specimen liquid flows into the first channel; joining a washing liquid to the rear end of the specimen liquid which stops in the first channel by flowing the washing liquid to a third channel that is converged to a connection portion of the second channel; and feeding the washing liquid to the first channel after the washing liquid is joined to the rear end.Type: GrantFiled: September 28, 2009Date of Patent: May 31, 2011Assignee: Fujifilm CorporationInventors: Yoshihiro Sawayashiki, Hideyuki Karaki

Patent number: 7951611Abstract: A card or insert having a plurality of recesses for a sample preparation device, the card containing cast-in-place composite and/or non-filled structures which are useful as sorptive or reactive media or for size-based separations. Any particular card size or configuration can be used, and the inclusion of a large amount of adsorptive particles in polymer is achieved while still maintaining the membrane three dimensional structure. In a first preferred embodiment, the composite structures comprise particles entrapped within a porous polymeric substrate, and are cast in-place into a plurality of recesses in an insert for a multi-well sample preparation device, thereby providing an effective platform for high throughput micromass handling.Type: GrantFiled: July 22, 2004Date of Patent: May 31, 2011Assignee: Millipore CorporationInventors: William Kopaciewicz, Cheryl Brucato

Patent number: 7951612Abstract: Contemplated herein is an automated microscope slide antigen recovery and staining apparatus and method that features a plurality of individually operable miniaturized pressurizable reaction compartments for individually and independently processing a plurality of individual microscope slides. The apparatus preferably features independently movable slide support elements each having an individually heatable heating plate. Each slide support element preferably supports a single microscope slide. Each microscope slide can be enclosed within an individual pressurizable reaction compartment. Pressures exceeding 1 atm or below 1 atm can be created and maintained in the reaction compartment prior to, during or after heating of the slide begins.Type: GrantFiled: May 24, 2006Date of Patent: May 31, 2011Inventors: Lee Angros, Thomas Lee Byers

Patent number: 7951613Abstract: Methods of use of Chaperonin 10 (Cpn10) are provided for regulating Toll-like receptor signaling and/or Toll-like receptor inducible immunomodulator secretion. Cpn10 negatively regulates Toll-like receptor agonist-induced pro-inflammatory cytokine and chemokine secretion, examples being IL-6 and RANTES, respectively. Cpn10 positively regulates Toll-like receptor agonist-induced anti-inflammatory cytokine and chemokine secretion, an example being IL-10. These immunoregulatory activities of Cpn10 may be useful in the treatment of diseases, disorders and conditions resulting from excessive pro-inflammatory cytokine and chemokine secretion. This invention also relates to producing, designing and/or screening Cpn10 agonists and antagonists according to their ability to regulate Toll-like receptor signaling and/or Toll-like receptor inducible immunomodulator secretion.Type: GrantFiled: September 3, 2009Date of Patent: May 31, 2011Assignee: CBIO LimitedInventors: Barbara Jane Johnson, Andreas Suhrbier, Dean Jason Naylor, Caroline Amanda Dobbin, Christopher Bruce Howard
