摘要:
Described is a method of simultaneously testing a plurality of compounds for activity comprising the steps of: (a) placing a plurality of the compounds into at least two arrays, each having a plurality of test zones, with multiple compounds in each zone; (b) determining the location of each compound in each test zone; (c) subjecting the array to a testing screen; and (d) ascertaining those compounds that had a positive response to the testing screen. Also described are apparatus for performing simultaneous testing of a plurality of compounds in a plurality of arrays containing the compounds to be tested for their activity.
摘要:
A process for producing cholesterol oxidase from a recombinant microorganism, the microorganism itself and its recombinant plasmid are disclosed. The cholesterol oxidase has a particular amino acid sequence, a high substrate affinity and a working pH in the acidic range. The gene for this cholesterol oxidase was derived from Brevibacterium sterolicum. The cholesterol oxidase is used for the quantitative determination of cholesterol.

The invention provides an improved method for quantitation of two target genes in a simultaneous PCR, without the need to determine limiting primer concentrations for both targets. In particular, the invention provides a method of quantitation of expression of a first and a second target protein-encoding nucleic acids using a PCR based assay in which amplification of nucleic acid is detected by release of a reporter fluorescent signal which is measured as a nomialized reporter value (“deltaRn”).
摘要:
A method of determining skin tissue cholesterol includes preparing a section of skin surface, applying a dosed amount of an enzyme-containing mixture onto the skin, exposing, evaluating the concentration of cholesterol in a reaction solution and calculating the concentration of skin cholesterol, wherein the area of contact of the skin with the mixture is limited on the section of the skin surface by means of a sealing vessel without a bottom with a base fixed on the skin, a mixture comprising 2.0-2.5 units of cholesteroloxidase, 0.04-0.06% by weight of sodium dezoxycholate, 0.1-0.2.% by weight of 3-(dodecyl-dimethyl-ammonium)-propanesulfonate in a buffer solution with pH=6.8 is used as the mixture, evaluating the concentration of cholesterol in the reaction solution is carried out by measuring the level of hydrogen peroxide. Measurements of the level of hydrogen peroxide may be carried out by immersing an electrochemical sensor or a colorimetric indicator in the reaction solution.

A method for quantifying LDL cholesterol, by which LDL cholesterol is separately quantified simply without requiring complicated centrifuge operation is disclosed. The method for quantifying cholesterol in low density lipoprotein according to the present invention comprises a first step of erasing cholesterol in high density lipoprotein, very low density lipoprotein and chylomicron in a test sample, and a second step of quantifying cholesterol remaining in the test sample.

The present invention provides a method for the quantitative determination of cholesterol in low density lipoproteins and a reagent kit for use therein. The present invention also provides a method for continuous fractional determination of cholesterol in high density lipoproteins and cholesterol in low density lipoproteins and a reagent kit for use therein, as well as a method for continuous fractional determination of cholesterol in high density lipoproteins and total cholesterol and a reagent kit for use therein.
摘要:
Disclosed is a method for quantifying cholesterol in HDL, which does not require complex fragmentation and separation operations, and by which the HDL cholesterol in test samples containing HDL and other lipoproteins such as low density lipoprotein (LDL), very low density lipoprotein (VLDL) and chylomicron (CM) may be quantified selectively, simply and accurately. The method for quantifying cholesterol in high density lipoprotein comprises a first step of erasing cholesterol in lipoproteins other than high density lipoprotein in a test sample, and a second step of adding a surfactant which specifically acts on high density lipoprotein to the product of the first step and enzymatically quantifying cholesterol in high density lipoprotein.
摘要:
A method for quantitatively determining LDL cholesterol, including the steps of adding to serum a surfactant selected from among polyoxyethylenealkylene phenyl ethers and polyoxyethylenealkylene tribenzylphenyl ethers and a cholesterol-assaying enzyme reagent so as to preferentially react cholestrols in high density- and very low density-cholesterols among lipoproteins, and subsequently determining the amount of cholesterol that reacts thereafter. This method can eliminate the necessity for pretreatments such as centrifugation and electrophoresis, enables the quantitative determination to be conducted in an efficient, simple manner, and can be applied to various automatic analyzers.

摘要:
A process for determining the identity of a target polypeptide using mass spectroscopy is provided. Depending on the target polypeptide to be identified, a process as disclosed can be used, for example, to diagnose a genetic disease or chromosomal abnormality, a predisposition to a disease or condition, or infection by a pathogenic organism; or for determining identity or heredity. Kits for performing the disclosed processes also are provided.
