The Angiotensin I Converting Enzyme (ACE) Activity Assay is based on the cleavage of a synthetic fluorogenic peptide. The measured fluorescence is directly proportional to the ACE activity present.
The reaction is summarized as follows: ACE
ACE Fluorogenic substrate ———————> Cleaved ACE Substrate + fluorescent product (λex 320nm/λem 405nm)
The ACE Positive Control in the kit can be used to screen for ACE inhibitors. This kit has a linear range of 1.5-110 mU of ACE activity.
Angiotensin Converting Enzyme (ACE) is a key component in the renin-angiotensin system (RAS), which is well known for its role in the regulation of blood pressure, electrolyte balance, and vascular remodeling. ACE is located mainly in the capillaries of the lungs, but can also be found in endothelial and kidney epithelial cells. This hormone system also regulates body fluids volume. Renin produces angiotensin I by cleaving several amino acids from angiotensinogen. ACE then hydrolyzes angiotensin I to yield active angiotensin II. Angiotensin II also stimulates the adrenal cortex to secrete aldosterone, which also causes an increase in blood pressure by stimulating sodium reabsorption by the kidney. Since ACE exhibits critical functions regulating RAS, ACE inhibition has become a promising approach for drug targeting in the treatment of cardiovascular diseases such as hypertension, heart failure, and diabetic nephropathy.
The detection range : 1.5-110 mU of ACE activity.
