α-Glucosidase (α-GC), also known as α-D-glucoside hydrolase, is widely distributed in nature, with a wide variety of species and different properties, and exists in almost all organisms. It has important physiological functions in carbohydrate metabolism in animals, plants and microorganisms. If α-GC is deficient, it leads to severe glycogen metabolism disorders and excessive glycogen accumulation, which can cause Pompah's disease (an autosomal recessive inherited glycogen storage disease, also known as glycogenosis type II). Long-term low α-GC activity in human tissues can cause muscle fiber destruction and muscle atrophy.
The detection principle of this kit is that the chromogenic substance generated by the substrate reaction catalyzed by α-glucosidase has the maximum absorption at 400 nm, and the enzyme activity of α-GC can be reflected by measuring its OD value at 400 nm.
