Used in biomedical research to quantify levels of angiotensin-converting enzyme (ACE) in biological samples such as serum, plasma, or tissue extracts. This ELISA kit enables researchers to study ACE activity in physiological and pathological conditions, particularly in relation to cardiovascular diseases, hypertension, and renal function. It is also employed in drug development to assess the efficacy of ACE inhibitors. The assay provides a sensitive and specific method for high-throughput screening in experimental models involving bovine-derived samples.
