Encompassing Amino Acids: 18-740
Applications: As an exopeptidase, ACE2 is useful for the study of enzyme kinetics and to screen for inhibitors. As a cell receptor for coronaviruses infection, including 2019-nCoV, ACE2 is useful for the study of protein-protein interactions.
Assay Conditions: Activity was determined using the Spike S1-Biotin (SARS-CoV-2): ACE2 TR-FRET Assay Kit (BPS Bioscience #79949). The ACE2 antibody was incubated with biotinylated Spike S1 (BPS Bioscience #100679), Eu-labeled ACE2 (BPS Bioscience #100705), and the dye-labeled acceptor for one hour. Then the TR-FRET signal was measured using a fluorescence reader.
