  • Publication number: 20100203549
    Abstract: This invention relates, e.g., to a set of calibrants for determining the amount in a sample of an analyte (e.g., a protein, such as a protein that has been post-translationally modified), comprising a plurality of calibrants, which contain a range of amounts (e.g., defined amounts and/or serial dilutions) of the analyte, spanning the expected amount of the analyte in the sample. In each of the calibrants, a defined amount of the analyte is present in the same suitable, biological diluent (e.g., a cell or tissue lysate, or a bodily fluid). In one embodiment of the invention, the diluent reflects the same or a similar biological milieu (proteins, lipids, serum proteins, serum matrix proteins, etc.) as that in the sample in which the analyte to be measured is present. In embodiments of the invention, a single calibrant (e.g., a cell lysate) may comprise as many as hundreds of analytes, and can be used for the quantification of those hundreds of analytes in a sample.

    Abstract: A new method to control the dispersibility of dried nanocrystalline cellulose (NCC) by controlling solution pH and ionic strength is provided; when stable, non-reswellable acid-form NCC (H-NCC) films are placed in concentrated sodium hydroxide solutions, they swell but do not disperse; while sodium-form NCC (Na-NCC) or other NCC films having neutral monovalent counterions readily disperse in pure water, Na-NCC films placed in hydrochloric acid and sodium chloride as well as sodium hydroxide solutions of sufficient ionic strength swell, but do not disperse; similar properties are observed for freeze-dried NCC products. The dispersibility of these NCC films is a function of the ionic strength and the identity of the electrolyte solutions to which they are exposed. NCC films are envisaged that have barrier properties in an electrolyte solution but that disintegrate or disperse when rinsed with pure water at the end of their useful lifespan.

  • Publication number: 20100048884
    Abstract: The invention relates to a process for hydrolyzing cellulose, comprising: (a) contacting cellulose with a fluid mixture comprising supercritical CO2 and sub-critical or near-critical water to form a reactant mixture at a first temperature and first pressure for a first time period, wherein a reaction occurs and forms one or more hydrolysis products; (b) quenching the reaction; and (c) recovering at least one hydrolysis product.

  • Publication number: 20100029926
    Abstract: The instant invention involves a process for enhancing molecular mass of biomass reactants. The process comprises first forming a substituted or unsubstituted furfural from a biomass. The substituted or unsubstituted furfural is then reacted with an activated methylene compound in the presence of a catalyst and, if desired, a solvent to form a Knoevenagel product. The product may then be hydrogenated to products containing an alcohol, ether, aldehyde, or ketone functional groups or to an olefinic or aliphatic species wherein as much as all of the oxygen and/or nitrogen has been removed.

  • Patent number: 7652131
    Abstract: The invention includes methods of processing plant material by adding water to form a mixture, heating the mixture, and separating a liquid component from a solid-comprising component. At least one of the liquid component and the solid-comprising component undergoes additional processing. Processing of the solid-comprising component produces oils, and processing of the liquid component produces one or more of glycerol, ethylene glycol, lactic acid and propylene glycol. The invention includes a process of forming glycerol, ethylene glycol, lactic acid and propylene glycol from plant matter by adding water, heating and filtering the plant matter. The filtrate containing starch, starch fragments, hemicellulose and fragments of hemicellulose is treated to form linear poly-alcohols which are then cleaved to produce one or more of glycerol, ethylene glycol, lactic acid and propylene glycol. The invention also includes a method of producing free and/or complexed sterols and stanols from plant material.

  • Publication number: 20100016575
    Abstract: A method for the production of a bacterial cellulose-containing formulation that lacks a carboxymethyl cellulose component. The method includes providing a bacterial cellulose product, mixing the bacterial cellulose product with a polymeric thickener and/or a precipitation agent, lysing the bacterial cells from the bacterial cellulose product or the mixture of the bacterial cellulose product and the polymeric thickener or precipitation agent, and co-precipitating the resultant mixture with a water-miscible non-aqueous liquid. The resultant bacterial cellulose formulation includes at least one bacterial cellulose material and at least one polymeric thickener. The bacterial cellulose formulation, may be used in food compositions.

  • Patent number: 7645874
    Abstract: This invention relates to a process for preparing bioabsorbable oxidized cellulose comprising combining cellulose material, with nitrogen dioxide and a nonaqueous solvent chosen from the class of perfluorinated tertiary amines. This invention also relates to a method of oxidizing cellulose material comprising introducing a solvent into the vessel, circulating the solvent through the cellulose material, adding nitrogen dioxide to said vessel containing the solvent and cellulose in the required amounts, circulating the solution for 7 to 24 hours while controlling the reaction temperature, and isolating the oxidized material. Preferably, isolation of the oxidized product is followed by first washing the oxidized cellulose material with cold water, then washing the oxidized cellulose material with an aqueous alcohol solution several times, then washing the material with 100% alcohol several times, and finally drying the oxidized material.
