    Abstract: Conjugates of 1,3-bis(1,4,7-triazacyclonon-1-yl)-2-hydroxypropanes with a variety of conjugating members are used in the formation of dinuclear metal complexes which bind to phosphate esters. By virtue of their conjugated forms, the complexes are incorporated into chromatographic media, affinity binding reagents, and dyes, which make the complexes useful in a wide range of assays, separations, and purifications. In addition, dinuclear metal complexes of 1,3-bis(1,4,7-triazacyclonon-1-yl)-2-hydroxypropanes that are not so conjugated are used in the detection of phosphate esters of biological species by either MALDI-TOF mass spectrometry or by dye displacement.

  • Patent number: 8128980
    Abstract: Disclosed is a novel water-soluble soybean polysaccharide which is produced by imparting a function of stabilizing a protein in a pH range around the isoelectric point of the protein to a water-soluble soybean polysaccharide. Also disclosed is a novel dispersion stabilizer which enables to stabilize the dispersion of a protein in a pH range around the isoelectric point of the protein. Further, disclosed is a acidic protein food/beverage comprising the dispersion stabilizer. A crosslinked product of a water-soluble soybean polysaccharide extracted from a soybean seed raw material can improve the dispersion stability of a milk protein in a pH range around the isoelectric point of the protein. By using the water-soluble soybean polysaccharide, an acidic protein food/beverage having a low viscosity can be produced.

  • Patent number: 7812006
    Abstract: The invention relates to conjugates derived from the reductive amination of the pneumococcus serotype 5capsular polysaccharide. The conditions for reductive amination differ from conventional conditions in that they make it possible to avoid the appearance of an undesirable compound which harms the immunogenicity of the conjugates. In carbon NMR spectrum, this undesirable compound is characterized by a resonance signal between 13 and 14 ppm. The aminated polysaccharides used to produce the conjugates therefore have a carbon NMR spectrum lacking a resonance signal between 13 and 14 ppm. The invention offers two conditions for reductive amination. According to a first method, the reductive amination is carried out at a slightly acidic pH (4-6.5) for at the very most 4 hours. According to a second method, the polysaccharide is first of all reduced, then fragmented and, finally, subjected to a reductive amination per se, under conditions which may or may not be conventional.

  • Publication number: 20100113764
    Abstract: Provided are methods for the solubilization of cellulose into soluble sugars without the need for high temperatures, high pressures, strong acid solutions, and/or added water. The produced sugars can be fermented into ethanol. In one embodiment, the method comprises contacting a cellulose-containing material with a solid acid material and agitating the cellulose-containing material and the solid acid material for a time sufficient to produce an aqueous solution comprising a quantity of soluble sugars.

  • Patent number: 7705135
    Abstract: Pectins having a combination of unexpectedly high molecular weights and low degrees of methylation have been isolated from Aloe vera plants, are superior gel pectins for forming calcium cross-lined gels. Such pectins can be obtained by extracting homogenized Aloe Vera plants or portions thereof. These pectins can be used to prepare pharmaceutical compositions comprising pharmacological agents for application to animals and humans, so as to provide controlled release of the pharmacological agent.

  • Patent number: 7691988
    Abstract: A method is provided for nucleic acid amplification with enhanced sensitivity. The method for enhanced sensitivity involves carrying out the amplification reaction in the presence of gellan. For instance, the method allows for the production of detectible amounts of PCR amplified DNA from at least 10 fold fewer target molecules than a comparable PCR reaction in absence of gellan.

  • Patent number: 7687249
    Abstract: The present invention relates to a process for the preparation of sulphated glycosaminoglycans derived from N— acetylheparosan which comprises: a) N-deacetylation and N-sulphation of the N-acetylheparosan polysaccharide prepared from natural or recombinant bacterial strain, preferably K5 E. coli, b) enzymatic epimerization with the glucuronyl C5-epimerase enzyme, c) partial O-sulphation followed by a partial O-desulphation, d) partial 6-O-sulphation, e) N-sulphation and an intermediate step of controlled depolimerization characterised by the fact that both O-sulphations (O-sulphation and 6O-sulphation) are partial. Furthermore the invention relates to the products obtained according to the process which show a ratio between the anti-Xa activity and anti-IIa activity equal to or higher than 1 and to compositions comprising said products in combination with suitable and pharmaceutically acceptable excipients and/or diluent.

  • Patent number: 7608436
    Abstract: A process for preparing saccharide oligomers uses an aqueous feed composition that comprises at least one monosaccharide or linear saccharide oligomer, and has a solids concentration of at least about 70% by weight. The feed composition is heated to a temperature of at least about 40° C., and is contacted with at least one catalyst that accelerates the rate of cleavage or formation of glucosyl bonds, such as enzyme or acid, for a time sufficient to cause formation of non-linear saccharide oligomers. A product composition is produced that contains a higher concentration of non-linear saccharide oligomers than linear saccharide oligomers.
