Used in biomedical research to quantify angiotensin-converting enzyme (ACE) levels in biological samples such as serum, plasma, or tissue homogenates. This kit supports studies related to the renin-angiotensin system, particularly in cardiovascular diseases like hypertension, heart failure, and kidney disorders. It is also applied in monitoring ACE activity changes in response to pharmaceutical treatments, including ACE inhibitors. Widely used in clinical research and drug development for its high sensitivity and specificity in detecting ACE concentration.
