摘要： A mutant-type uricase, PEG modified mutant-type uricase, and application thereof. The mutant-type uricase has a cysteine residue introduced by recombination, the cysteine residue is located at an inactive region of the uricase, and one or more PEGs are coupled to the mutant-type uricase. The resulting PEGylated mutant-type uricase has characteristics of a half-life extension, product uniformity, and stable enzyme activity. Therefore, the present invention has a wide future application range.

摘要： A device is disclosed for conducting a non-invasive analysis of a bodily fluid to determine the presence and level of a certain constituent carried by the bodily fluid. An indicator formulation of the device changes color in response to exposure to the constituent to provide a visible indication of the presence and level of the constituent carried by the bodily fluid. A carrier substrate of the device is constructed of a material having voids providing a high void volume within the substrate. The device is made by applying a chromagen to the carrier substrate to create a chromagen-laden carrier member. Then, a selected reagent having a particular constituent-specific formulation is applied to the chromagen-laden member. The selected reagent then combines with the chromagen thereby establishing the indicator formulation within the carrier substrate in place for reception of a sample of the bodily fluid.

摘要： A method of determining the number of bacteria in a sample which involves introducing a sample containing bacteria into a tubular filtering vessel holding therein a hydrophobic filter for bacterial detection, a coloring composition is disposed on the side of the filter where the sample is introduced into the vessel, and a support for the filter is disposed on the opposite side of the filter from the coloring composition. The bacteria is subjected to and the sample is filtered dyeing sample by suction from the support to collect the dyed bacteria on the filter and remove the excess of coloring matter. The number of the bacteria in the sample is determined from the degree of staining of the filter.

摘要： A method for detecting an analyte in a sample uses both the specificity of an enzymatic reaction and the separation power of capillary electrophoresis. In general, the method comprises: (1) subjecting a first aliquot of the sample to an analytical technique such as capillary electrophoresis, which generates a first output such as an electropherogram; (2) reacting a second aliquot of the sample in an enzyme-catalyzed reaction converting the analyte into a product, the product being detectable by the analytical technique; (3) subjecting the second aliquot to the analytical technique to generate a second output; (4) in the case of electrophoresis, measuring the absorbance of the first and second outputs (electropherograms) as a function of migration distance along the electropherogram at at least one wavelength at which either the analyte or the product absorbs to produce a first absorbance scan and a second absorbance scan; and (5) comparing the first absorbance scan with the second absorbance scan to detect the analyte. The reaction can involve a coenzyme and the analytical technique can be directed to the coenzyme. Alternatively, at least two enzymes can be used, the first enzyme generating a first product that is then acted upon by the second enzyme.

摘要： A method, reagent mixture and test kit are provided for testing a urine sample for the presence of bacterial or somatic cells, by reacting a urine sample with a catalase-free alkaline protease enzyme and a detergent compatible therewith, so as to disrupt any such cells present in the sample and release active catalase therefrom. The presence of catalase is detected by the formation of foam upon the addition of H.sub.2 O.sub.2. The reaction of the sample with the protease enzyme and the detergent is conducted in the presence of: (a) a buffer providing for a pH of about 8.5 to about 9; and optionally (b) one or more additional solutes; the total concentration of components (a) and (b), when present, being from about 0.02M to about 0.4M.

摘要： A method for quantitative analysis of hydrogen peroxide at a high precision is disclosed. The method comprises reacting a divalent cobalt compound with hydrogen peroxide in the presence of peroxidase or a substance similar to peroxidase to produce a trivalent cobalt compound, reacting the trivalent cobalt compound thus produced with a trivalent cobalt indicator to produced a colored complex, and subjecting the colored complex to colorimetric quantitative analysis. The method enables various enzymatic activities producing hydrogen peroxide by the reaction with substrates as well as the amount or activity of substances involving the known enzymatic reactions linked with such enzymatic reactions, of enzymes and coenzymes, to be quantitatively determined very easily at a high sensitivity at a wavelength of above 600 nm without the interference of hemoglobin, bilirubin, or turbidity.
