Abstract

The invention relates to a kit for diagnosing / measuring glycine by utilizing the technologies of the enzymic colorimetry 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 measuring the concentration of the glycine, and belongs to the technical field of medical / food inspection and measurement. The main components of the kit include a buffer solution, coenzyme, a 2-ketoglutaric acid, glycine aminotransferase, glutamate dehydrogenase and a stabilizer. Through mixing a sample and the reagent by a certain volume ratio, a series of enzymatic reactions occur, then the reactant is placed under an ultraviolet / visible light analyzer, and the degree / velocity of the increase in absorbance at 340 nm of the dominant wavelength is detected, thereby measuring the active concentration of the glycine.

Description

technical field [0001] The invention relates to a glycine diagnosis / measurement kit, and at the same time, the invention also relates to a method for measuring glycine concentration, which belongs to the technical field of medicine / food inspection and determination. Background technique [0002] Glycine is an important fine chemical intermediate, widely used in pesticide, medicine, food, chemical fertilizer, feed and other industries. According to the preparation process of glycine and the purity of the product, it can be divided into four specifications: food grade, pharmaceutical grade, feed grade and industrial grade. [0003] Among the more than 20 kinds of amino acids, glycine is the simplest one. It is a component of protein and is a non-essential amino acid. The "Hygienic Standards for the Use of Food Additives" stipulates that glycine is allowed to be used in seasonings and soybean milk, and the maximum usage is 1g / kg. The results of a special supervision and inspe...
