Used to measure glucose-6-phosphate dehydrogenase (G6PDH) enzyme activity in rat biological samples such as tissue homogenates, blood, or cell lysates. This assay is commonly applied in research settings to evaluate oxidative stress, red blood cell function, and metabolic disorders in rat models. It is also utilized in toxicology studies to assess drug-induced hemolysis or liver damage, as G6PDH plays a key role in the pentose phosphate pathway, protecting cells from oxidative damage. The kit enables high-throughput, quantitative analysis, making it valuable in preclinical research and pharmaceutical development.
