Used in biomedical research to measure angiotensin I levels in mouse samples, this ELISA kit helps study the renin-angiotensin system (RAS), which regulates blood pressure and fluid balance. It is commonly applied in hypertension, cardiovascular disease, and kidney function studies. Researchers use it to evaluate drug effects on RAS, assess hormonal changes in disease models, and support preclinical investigations involving mouse physiology. The assay provides a sensitive and specific way to quantify angiotensin I in plasma or serum, enabling accurate tracking of RAS activation in experimental conditions.
