摘要： The present invention relates to a method for quantification of amino acids using a cell-free protein synthesis system. Specifically, the present invention relates to a method for quantification of amino acids, comprising: (a) preparing a reaction mixture for cell-free protein synthesis without target amino acids; (b) performing cell-free protein synthesis by mixing an assay sample containing target amino acids with the reaction mixture for cell-free protein synthesis; (c) measuring the signal intensity of the synthesized protein; and (d) calculating the concentration of the target amino acids by comparing the measured signal intensity with the standard concentration curve for each amino acid according to the protein signal produced using a standard sample, a method for providing information for diagnosing an amino acid metabolism-related disease using the same, a method for screening a material for prevention or treatment of an amino acid metabolism-related disease, and a method for screening a transaminase substrate. The method for quantification of amino acids according to the present invention can quantify amino acids in a short time at a low cost, and thus can be useful in various industries.

摘要： There is provided a novel quantification method for quantifying a concentration of EAP, which is a biomarker of depression, an enzyme for quantitation, a composition for quantitation, a kit for quantitation or a sensor for quantitation. There is provided a quantification method of ethanolamine phosphate by adding oxidoreductase to a sample containing ethanolamine phosphate. A mediator may be reduced by adding the oxidoreductase, and the reduced mediator may be reacted with a reagent to determine a concentration of ethanolamine phosphate. In addition, hydrogen peroxide produced by adding the oxidase as the oxidoreductase may be reacted with a reagent to determine a concentration of the ethanolamine phosphate.

摘要： An object of the present invention is to provide a blood analysis method and a blood test kit, which are for performing quantitative analysis of components by precisely obtaining a dilution factor. According to the present invention, provided is a blood analysis method including a step of diluting a collected blood sample with a diluent solution; a step of determining a dilution factor by using a normal value of a normal component which is homeostatically present in blood; and a step of analyzing a concentration of a target component in the blood sample, in which the blood analysis method uses a member selected from the group consisting of a first storing instrument for storing a diluent solution, a separation instrument for separating and recovering blood plasma from the blood sample diluted with the diluent solution, a holding instrument for holding the separation instrument, a second storing instrument for storing the recovered blood plasma, and a sealing instrument for keeping the stored blood plasma within the second storing instrument, in which the diluent solution defines an amount of the normal component which is derived from the diluent solution and/or the members and may be contained in the diluent solution, and in which a volume of the blood sample is 50 μL or less, and a dilution factor of a blood plasma component in the blood sample is 14 times or more.

摘要： The invention relates to a device and a method for measuring neurotransmitters in the brain dialysate of mammals using enzymatic reactors specific to a certain neurotransmitter, which generate fluorescent derivatives when mixed. The mixture is introduced into an incubation chamber and passes through a temperature controlling system in order to set it to the optimum enzymatic reaction temperature, and the fluorescent derivative generated is passed through a flow fluorescence cell located inside the incubation chamber, where the liquid is impacted with a laser light source via an optical fiber. The fluorescence emitted is captured by a fluorescence detector that sends it to a processing system in order to obtain the corresponding values.
