Abstract

The invention relates to a kit for diagnosing/mensurating manganese ions by utilizing the technologies of the enzymatic cycling amplification method, the enzymic colorimetric method and the enzyme linked immunosorbent assay. The invention further relates to a method, a principle and the composition and the components of a reagent for mensurating the concentration of the manganese ions, and belongs to the technology field of medical/food/environmental inspection and measurement. The main components of the kit include a buffer solution, reduced coenzyme, oxaloacetic acid, ammonia ions, oxaloacetic decarboxylase, alanine dehydrogenase, glycine oxidase, peroxidase, a reduced chromogen combination and a stabilizer. Through a series of enzymatic reactions, the colorless reduced chromogen combination is finally oxidized into the colored dyes, thereby mensurating the content of the dyes at 400nm-700nm of the wavelength by a visible light analyzer and further reflecting the concentration of the manganese ions directly.

Description

technical field [0001] The invention relates to a manganese ion diagnosis / measurement kit, and at the same time, the invention also relates to a method for measuring manganese ion 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 many enzyme activation reactions, Mn 2+ and Mg 2+ Can replace each other. [0003] Commonly used graphite furnace atomic absorption spectrophotometry, atomic emission ICP-OES. Neutron exc...
