ACE Liquid

 

 

ACE Liquid

An easy procedure to measure Angiotensin Converting Enzyme.
ACE Liquid is Mono-reagent method for the determination of Angiotensin Converting Enzyme (ACE) in human serum and plasma

 

SUMMARY

ACE is a zinc dependent peptidase which has a major role in the metabolism of vasoactive peptides and hence in the regulation of blood pressure, converting the relatively inactive decapeptide Angiotensin I to the potent vasoconstrictor Angiotensin II.

Serum ACE is often elevated in patients with untreated active sarcoidosis, an inflammatory disease of unknown origin characterized by the formation of small clumps affecting eyes, lungs, lymph nodes and skin.

The measurement of ACE levels can assist in diagnosing Sarcoidosis and in monitoring the effectiveness of steroid therapy.

Other diseases in which ACE may be elevated include Gaucher’s disease, leprosy, tuberculosis and pathologic conditions involving lung and liver diseases.

PRINCIPLE

The hydrolysis of FAPGG (furylacryloylphenylalanine-glycylglycine) to FAP (furylacryloylphenylalanine) is catalyzed by ACE enzyme. Hydrolysis of FAPGG results in a decrease in absorbance at 340 nm. The ACE activity in the sample is determined by comparing the sample reaction rate to that obtained with the Sentinel ACE calibrator.
