The ACE2 Inhibitor Screening Kit can be used for Inhibitor Screening where ACE2 inhibits ACE2 activity by utilizing its ability to cleave the Synthetic MCA Based Peptide substrate to release Free Fluorophore. The MCA emitted by the action of ACE2 can be easily quantified using a fluorescent Microplate Reader, and the ACE2 Specific Inhibitor reduces fluorescence by decreasing the MCA emission by degrading the function of ACE2
