Patent number: 6559296Abstract: The present invention relates to an apparatus for detecting nucleic acid molecules such as target DNA molecules and mRNA molecules by using a DNA probe, and provides a DNA capillary, comprising a fluid passageway formed of a cylindrical capillary made of glass, a plurality of independent probe regions formed in the inner wall of the fluid passageway, and DNA probes each immobilized in the probe region, the immobilized DNA probes differing from each other. For performing the measurement, a sample is introduced through an open portion into the capillary so as to perform reaction and, then, fluorimetry.Type: GrantFiled: February 21, 2001Date of Patent: May 6, 2003Assignee: Olympus Optical Co., Ltd.Inventor: Akira Suyama

Patent number: 6559297Abstract: Novel synthases and the corresponding nucleic acids encoding such synthases are disclosed herein. Such synthases possess an active site pocket that includes key amino acid residues that are modified to generate desired terpenoid reaction intermediates and products. Synthase modifications are designed based on, e.g., the three-dimensional coordinates of tobacco 5-epi-aristolochene synthase, with or without a substrate bound in the active site.Type: GrantFiled: June 29, 2001Date of Patent: May 6, 2003Assignees: The Salk Institute for Biological Studies, The University of Kentucky Research FoundationInventors: Joseph Chappell, Kathleen R. Manna, Joseph P. Noel, Courtney M. Starks

Patent number: 6559298Abstract: Disclosed are a polypeptide (including that in soluble form) as receptor for a novel cytokine, i.e., interleukin-18, a DNA encoding the polypeptide, and the uses of the polypeptide including pharmaceutical and neutralizer to interleukin-18. Pharmaceuticals with the polypeptide is useful to treat and prevent autoimmune and allergic disease because it suppresses and regulates excessive immunoreaction.Type: GrantFiled: April 24, 2000Date of Patent: May 6, 2003Assignee: Kabushiki Kaisha Hayashibara Seibutsu Kagaku KenkyujoInventors: Kakuji Torigoe, Takanori Okura, Masashi Kurimoto

Patent number: 6559300Abstract: A water-soluble, biodegradable hydroxyalkyl cellulose-2-hydroxycarboxylic acid ester is disclosed. The hydroxyalkyl cellulose-2-hydroxycarboxylic acid ester has: (i) a molecular degree of substitution of the hydroxyalkyl group of less than 1.5 (MShydroxyalkyl<1.5); and (ii) a molecular degree of substitution of the 2-hydroxycarboxylic acid group of greater than 0.4 and less than 3 (0.4<MS2-hydroxycarboxylic acid<3). Also described is a method of preparing the hydroxyalkyl cellulose-2-hydroxycarboxylic acid ester, and methods of using it, e.g., as a consistency regulator in at least one of foodstuffs, cosmetics, building materials, paints and strippers.Type: GrantFiled: January 11, 2000Date of Patent: May 6, 2003Assignee: Wolff Walsrode AGInventors: Joachim Simon, Hanns-Peter Müller, Rainhard Koch, Volkhard Müller, Jürgen Engelhardt, Klaus Szablikowski, Wolfgang Koch

Patent number: 6559301Abstract: Dispersions of pigment, such as calcium carbonate, titanium dioxide and types of clay, can be effectively stabilized by the use of carboxyl-containing fructan in an amount of 0.05-10% by weight, based on the dispersion, which fructan contains 0.5-3 carboxyl groups per mono-saccharide unit. The carboxyalkyl groups are in particular carboxymethyl groups, but the carboxyl groups can also be carboxyl groups obtained entirely or partially by oxidation. The carboxymethylfructan gives results which are comparable to or better than those obtained with the polyacrylates which are less desirable from the standpoint of health and environment.Type: GrantFiled: December 11, 2000Date of Patent: May 6, 2003Assignee: Cooperatie Cosun U.A.Inventors: Hendrika Cornelia Kuzee, Hendricus Wilhelmus Carolina Raaijmakers

Patent number: 6559302Abstract: Various polysaccharides are prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of mineral acids such as phosphoric, hydrochloric and/or sulfuric acid. In one embodiment, polydextrose is prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of low levels, i.e., from about 0.001% to about 0.09%, more narrowly from about 0.01% to about 0.06%, phosphoric acid. In other embodiments, other mineral acids or mixtures thereof may be employed. In alternate embodiments, a combination of mineral and organic carboxylic acids such as citric acid are employed. Because of the low levels of catalyst used in certain preferred embodiments, minimal or no off-flavors and little color are formed during the course of the reaction.Type: GrantFiled: November 18, 1999Date of Patent: May 6, 2003Inventors: Pankaj Shashikant Shah, Stuart Andrew Shaw Craig, Christina Sue Morrill, Michael Torrey Wuesthoff

Patent number: 6559303Abstract: Novel macrocyclic compounds are constructed to include large cyclic structures that are interrupted by at least one ring system. Each interrupting ring system includes two bridgehead atoms. Bridgehead atoms are bonded to one or more bridges that interconnect one or more ring systems thereby forming a large cyclic structure. Located in each bridge are two or more nitrogenous moieties that are derivatized with chemical functional groups. The ring systems can include further nitrogenous moieties, either as ring atoms or on pendant groups attached to the ring. These can also be derivatized with chemical functional groups. The totality of the chemical functional groups imparts certain conformational and other properties to the macrocyclic compounds. In accordance with certain embodiments of the invention, libraries of such macrocyclic compounds are prepared utilizing permutations and combinations of the chemical functional groups and the nitrogenous moieties to build complexity into the library.Type: GrantFiled: April 9, 1999Date of Patent: May 6, 2003Assignee: ISIS Pharmaceuticals, Inc.Inventor: Phillip Dan Cook
