Mca-Ala-Pro-Lys(Dnp)-OH, a specific ACE2 quenched fluorogenic substrate, can be used to detect ACE2 activity, such as urinary, heart and lung[1][2].

In Vitro

The activity of ACE2 enzyme detected by: the fluorescent peptide substrate Mca-AlaPro-Lys (Dnp)-OH is hydrolyzed by ACE2 and its product is detected by the active fluorescence resonance energy transfer method[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
