Abstract

The present invention belongs to the field of medical laboratory technology, and in particular relates to an alpha-amylase detection reagent and application thereof. The reagent comprises a reagent R1 and a reagent R2; the reagent R1 is mainly composed of an MES buffer, NH4Cl, CaCl2, a surfactant and a preservative; the R2 reagent consists of an MES buffer, a 2-chloro-4-nitrobenzene-maltotriose and a preservative. The alpha-amylase detection reagent provided by the invention does not contain NaN3, does not lead to alpha-amylase allosterism in the determination process, and can reduce the error in measurement results; at the same time, the test does not need additional tool enzyme, and has short delay time; the test results have good repeatability and stability. Therefore, the invention is conducive to the clinical application of alpha-amylase detection reagent.

Description

technical field [0001] The invention belongs to the technical field of medical testing, and in particular relates to an α-amylase detection reagent and application thereof. Background technique [0002] The scientific name of α-amylase is 1,4-α-D-glucan-4-glucanohydrolase, which is an enzyme synthesized by epithelial cells with secretory function in the salivary gland and pancreas. α-Amylase is an important biochemical marker for detecting acute pancreatitis. Therefore, the determination of the concentration of α-amylase has important clinical significance. [0003] According to statistics, there are more than 200 methods for the determination of α-amylase, which are mainly divided into six categories: viscometry, iodometric method, turbidimetric method, saccharification method, dye release method and fluorescence method. With the continuous in-depth research on α-amylase assay methods, many new assay methods have emerged. At present, the most widely used method is the et...
