Description
Glucose-6-phosphate dehydrogenase (G6PDH; EC 1.1.1.49) is widely present in animals, plants, microorganisms and cultured cells. It is a key enzyme in the pentose phosphate pathway, and maintains the intracellular level of NADPH. NADPH in turn maintains the glutathione level in cells, thereby protecting cells from oxidative damage. Therefore, the activity of G6PDH can reflect the biosynthesis and antioxidant capacity of organisms to a certain extent.
G6PDH catalyzes the oxidation of glucose-6-phosphate to 6-phosphogluconolactone, and simultaneously reduces NADP⁺ to NADPH. The traditional method detects the absorbance of NADPH at 340nm. Due to the low molar extinction coefficient (ε) of NADPH, this method has low sensitivity and is severely susceptible to interference.
This kit provides a simple, sensitive and rapid assay method: the NADPH produced by this enzymatic process reacts with a specific chromogenic reagent to produce a colored substance with a maximum absorption peak at 450nm. The G6PDH enzyme activity is calculated by detecting the increase rate of absorbance at 450nm.
