Used in biomedical research to measure angiotensin-converting enzyme (ACE) activity in mouse samples, particularly in studies related to the renin-angiotensin system. Helps assess lung, kidney, or cardiovascular function in mouse models. Commonly applied in hypertension, heart failure, and inflammation studies. Enables high-throughput screening of drug effects on ACE levels in serum, tissue homogenates, or cell cultures. Provides a sensitive and specific way to quantify ACE activity, supporting mechanistic insights in physiological and pathological processes.
