Product details:
ACE Assay Kit (Angiotensin I Converting Enzyme) (ab239703) utilizes an active ACE1 to cleave a synthetic
-aminobenzoyl peptide (Abz-based peptide) substrate to release a fluorophore. The released Abz can be easily quantified using a fluorescence microplate reader. This assay kit is simple, rapid and can detect ACE activity as low as 10 mU in biological samples, such as lung, heart and kidney tissue, and serum and plasma. It can also be used to determine the enzymatic activity of purified ACE1.
This product is manufactured by BioVision, an Abcam company and was previously called K227 Angiotensin I Converting Enzyme Activity (ACE1) Assay Kit (Fluorometric). K227-100 is the same size as the 100 test size of ab239703.
The Safety Datasheet for this product has been updated for certain countries. Please check the current version in the Support and downloads section.

Angiotensin Converting Enzyme 1 also known as ACE1 or ACE is an important enzyme in the renin-angiotensin system. This enzyme exhibits a significant role in blood pressure regulation. ACE1 is a zinc-metallopeptidase with a molecular weight of approximately 130 kDa. It converts angiotensin I into the potent vasoconstrictor angiotensin II a critical function in cardiovascular physiology. ACE1 is widely expressed in endothelial cells particularly in the lungs kidneys and the small intestine.
Biological function summary
The enzyme generates angiotensin II by cleaving angiotensin I. Angiotensin II an important effector peptide impacts cardiovascular and renal systems influencing vasoconstriction and fluid balance. While not directly forming a complex ACE1's activity increases the potency of angiotensin II which binds to angiotensin II receptors to exert its effects therefore indirectly forming a functional signaling complex.
Pathways
ACE1 plays a central role in the renin-angiotensin system and the kallikrein-kinin system. The enzyme's activity boosts angiotensin II production which connects it to the regulation of blood pressure via the renin-angiotensin pathway. ACE1 also indirectly interacts with proteins like bradykinin by degrading them modulating kinin-related functions and influencing inflammation and tension in vascular smooth muscle.
Understanding ACE1 is important for addressing hypertension and congestive heart failure. ACE1's conversion of angiotensin I to angiotensin II means overactivity can cause elevated blood pressure leading to hypertension. This makes ACE inhibitors such as lisinopril and ramipril therapeutic for these conditions. Furthermore its connection with aldosterone production places ACE1 in relevance to heart failure as excessive aldosterone can cause detrimental remodeling of cardiac tissue.
