Description

technical field [0001] The invention belongs to the field of life sciences and relates to a kit, in particular to a kit for measuring the activity of uridine diphosphate glucose pyrophosphorylase and a method thereof. Background technique [0002] UDP-glucose pyrophosphorylase is a key enzyme in the process of glycogen synthesis in organisms. Catalyzes the activation of glucose before the synthesis of glycogen from glucose, and synthesizes glucose-1-phosphate and UTP molecules into UDP-glucose (UDPG). [0003] At present, the determination method of uridine diphosphate glucose pyrophosphorylase is mainly the enzyme coupling method, and the extraction methods are not the same, and the extraction methods reported in many literatures are cumbersome, the components are complex, the measurement system is large, and the operation is not simple and fast enough. Now it is necessary to specially develop a kit that can easily, quickly and accurately measure uridine diphosphate glucos...
