Abstract

The invention provides a kit for detecting glucose-6-phosphate isomerase and a use method of the kit, and belongs to the technical field of enzyme detection. The kit comprises a first reagent and a second reagent, wherein the first reagent uses Tris buffer as a solvent and comprises adenosine triphosphate, beta-nicotinamide adenine dinucleotide trihydrate, a protective agent and a preservative; the second reagent uses the Tris buffer as the solvent and comprises magnesium chloride, fructose-6-phosphate, glucose-6-phosphate dehydrogenase, a stabilizer and the preservative; and the concentrationof the Tris buffer is 50-500 mmol/L. The kit provided by the invention can obtain a result of detecting glucose-6-phosphate isomerase at 6 min 20 s to 9 min 40 s, thereby shortening detection time.

Description

technical field [0001] The invention relates to the technical field of enzyme detection, in particular to a kit for detecting glucose-6-phosphate isomerase and a method for using the kit. Background technique [0002] Glucose-6-phosphate isomerase (GPI; EC 5.3.1.9) is a kind of natural protein with multifunctional biological activities, which is involved in the pentose phosphate pathway of sugar metabolism and glycolysis, Catalyze the interconversion of glucose 6-phosphate (G 6-P) and fructose-6-phosphate (F-6-P), thereby catalyzing the isomerization of F-6-P into G 6-P. PGI has multiple functions: In the cell, PGI plays a key role in glycolysis and gluconeogenesis; outside the cell, PGI (also known as autocrine motor factor, Autocrine Motility Factor (AMF)) acts as a cytokine to stimulate cells Movement, and is associated with tumorigenesis and metastasis. [0003] In the prior art, mainly the Elisa antigen antibody is used to detect the content of glucose 6 phosphate is...
