Used to measure the activity of CYP7A1 enzyme in rat liver samples, this ELISA kit supports research on cholesterol metabolism and bile acid synthesis. It enables scientists to evaluate how drugs, diets, or diseases affect the regulation of CYP7A1, a key enzyme in the conversion of cholesterol to bile acids. Commonly applied in metabolic studies, toxicology research, and drug development to assess liver function and identify potential treatments for hypercholesterolemia or liver disorders. The assay provides a quantitative, high-throughput method suitable for lab research use only.
