Used in biomedical research to quantify angiotensinase activity in biological samples such as serum, plasma, and tissue homogenates. Helps in studying the regulation of the renin-angiotensin system, which plays a key role in blood pressure control and fluid balance. Widely applied in hypertension, cardiovascular disease, and kidney function studies. Enables researchers to assess enzyme levels in experimental models and evaluate potential therapeutic interventions targeting angiotensin metabolism.
