Abstract: This invention relates generally to the field of homocysteine detection. In particular, the invention provides a method for determining homocysteine presence or concentration in samples, which method comprises: contacting a sample containing or suspected of containing Hcy with a Hcy co-substrate and a Hcy converting enzyme in a Hcy conversion reaction to form a Hcy conversion product and a Hcy co-substrate conversion product; and assessing the Hcy co-substrate conversion product to determine the presence, absence and/or amount of the Hcy in the sample. A kit for assaying homocysteine based on the same principle is also provided.
Abstract: The invention relates to foodstuff and animal feed which contain resistant starch on the basis of water-insoluble linear ?-1,4-D-glucans. The invention also related to the utilization of resistant starch on the basis of water-insoluble linear ?-1,4-D-glucans as medicaments.
Abstract: A diagnostic test kit for detecting the presence or quantity of an enzyme or enzyme inhibitor is provided. The diagnostic kit utilizes reactive complexes to facilitate the detection of the enzyme or enzyme inhibitor. The reactive complexes include a substrate joined (e.g., covalently bonded, physically adsorbed, etc.) to a reporter and magnetic substance. In one embodiment, for example, a peptide, protein, or glycoprotein substrate is joined to a reporter (e.g., dyed latex particle) and magnetic particle. In this embodiment, the substrate provides a cleavage target for a proteolytic enzyme. Specifically, upon contacting the reactive complexes, the proteolytic enzyme cleaves the substrate and releases the reporter and/or magnetic particle. The signal exhibited by the released reporters may then be used to indicate the presence or quantity of an enzyme or enzyme inhibitor within the test sample.

Abstract: A method for producing a purified Auricularia auricula Polysaccharide (AP) extract of Auricularia auricula (AA). A hydrated predetermined amount of AA is filtered and extracted, producing a first pre-extract. A plurality of additional hydrated predetermined amounts of AA is separately filtered and extracted to produce a plurality of additional pre-extracts. The pre-extracts are combined to form a first extract. The first extract is concentrated and suspended, forming a precipitate. The precipitate is purified to form a first filtrate, and repurified to form a second filtrate. The first and second filtrates are combined to form a first combined filtrate, which is concentrated, purified and dried to form a concentrated extract. The concentrated extract is purified to form a third filtrate, and repurified to form a fourth filtrate.
Abstract: The ability to efficiently determine the state of enzyme expression in cells has long been desired as material to the diagnosis of disease. This invention relates to cytoenzymology, and more particularly to improved reagents for use in cell-based assays, especially those using fluorogenic substrates.

Abstract: Disclosed is an ionic liquid-coated enzyme, wherein the ionic liquid is an organic salt which presents as a liquid phase at a temperature of about 150° C. or below. The ionic liquid-coated enzyme according to the present invention remarkably improves enzyme functions, such as enantioselectivity and stability, when the enzyme which may be lipase is coated with an ionic liquid. Further, even in the case of when the ionic liquid-coated enzyme is reused, the enantiomeric excess, enantioselectivity, and activity are not degenerated. The coated enzyme is usable as a catalyst for providing a chiral intermediate required in the synthesis of chiral pesticides, medicines, natural chemicals, and so on.
