Used in biomedical research to measure angiotensin II levels in rat samples, this ELISA kit helps study the renin-angiotensin system (RAS) involved in blood pressure regulation and fluid balance. It is widely applied in hypertension, cardiovascular disease, and kidney function studies. Researchers use it to evaluate the effects of drugs or experimental treatments on angiotensin II concentration in serum, plasma, or tissue samples. The kit enables high-throughput, quantitative analysis with high sensitivity and specificity, making it essential in pharmacological and physiological research involving the RAS pathway.
