Used to measure aldehyde dehydrogenase (ALDH) enzyme activity in rat biological samples such as tissue homogenates, blood, or cell lysates. This kit is commonly applied in toxicology studies, liver function assessment, and oxidative stress research where ALDH plays a key role in detoxifying aldehydes. It enables researchers to quantify ALDH activity in experimental models of liver disease, alcohol metabolism, and drug-induced organ damage. The assay is useful in preclinical studies evaluating hepatoprotective agents or environmental toxin exposure. Results are typically read using a microplate reader, allowing high-throughput analysis in research laboratories.
