Abstract

The invention relates to a manganese diagnostic/testing reagent kit using enzymatic colorimetric method and enzymic linkage technology as well as method for testing concentration of manganese as well as composition and content of the reagent, belonging to technical field of medicine/food/environment test. The invention is characterized in that composition in the reagent kit comprises buffer solution, reduction coenzyme, oxaloacetic acid, ammonium, oxaloacetic acid decarboxylase, alanine dehydrogenase and stabilizing agent; the sample is mixed with the reagent according to specified ratio to generate a series enzymatic reactions, then the reactant is arranged under a ultraviolet/visible light analyzer to test the decrease speed of absorbance at wavelength of 340nm, thereby the manganese concentration can be tested. The invention has the advantages that the test results can be easily obtained using ultraviolet/visible light analyzer.

Description

technical field [0001] The invention relates to a manganese diagnosis / measurement kit, and at the same time, the invention also relates to a method for measuring manganese concentration, which belongs to the technical field of medicine / food / environmental inspection and determination. Background technique [0002] As a trace element, manganese is an indispensable and necessary component in the human body, and it is also a substance that is toxic to the human body. In the natural state, it exists in divalent, trivalent and tetravalent forms, and the lower the degree of oxidation, the higher the toxicity. There are generally eight different oxidation states of manganese. The biological significance of manganese is its diverse functions as a cofactor in the human body. However, in the activation of many enzyme reactions, Mn 2+ and Mg 2+ Can replace each other. [0003] Commonly used graphite furnace atomic absorption spectrophotometry, atomic emission ICP-OES. Neutron exci...
