    摘要: PROBLEM TO BE SOLVED: To provide a method for assaying a substance designed to mitigate the influence of the other components coexisting therewith in a specimen, thus useful in clinical diagnoses, and to provide a reagent for the above method. SOLUTION: This method for assaying a substance is characterized by comprising the following practice: the substance in a specimen is brought into a stoichiometric quantity of hydrogen peroxide by making use of an enzymatic reaction, the hydrogen peroxide is then reacted with a chromogen in the presence of a peroxidase and also a compound of the general formula (I) [R1 and R2 are each H or a (substituted) lower alkyl; R3 is H or joined with R1 to form NH-(CH2)n as R3-R1 (wherein, n is an integer of 2-4); R4 is a single bond or alkylene; R5 is O- or R6-X-(R6 is an optionally substituted alkylene; X is COO, SO2O or OPO2O); Y is R7-NH (R7 is an optionally 1-3 hydroxy-substituted cholanoyl group)], and a colorimetric determination is made by measuring the absorption in the visible region of the resulting colored reaction liquid by the use of an automatic analyzer.

    摘要: PROBLEM TO BE SOLVED: To accurately measure ADP by previously deleting the ADP present in a test solution or the ADP present in a reaction liquid or formed by the reaction, allowing ADP-depending hexokinase to act on the deleted test solution, and measuring the product amount. SOLUTION: This method for measuring one of an enzyme forming ADP in a test solution or a substrate thereof by using an enzymatic reaction comprises a step for previously deleting the ADP present in a test solution or the ADP present in the first reaction liquid or formed by the first reaction by using pyruvic acid kinase or creatine kinase in the presence of magnesium ion and substrate for the ADP, a step for allowing ADP-depending hexokinase catalyzing a reaction of the formula to act on the ADP formed by the second reaction, and a step for measuring the amount of the produced glucose-6- phosphate or AMP to readily measure the objective ADP in high accuracy.
