Biochem/physiol Actions

Kinetically preferred fluorogenic substrate for detecting SARS-CoV and SARS-CoV-2 main proteases (Mpro; 3CLpro) activity (ex 380+/-20 nm, em 500+/-20 nm).
Ac-QS1-AFC or Ac-Abu-Tle-Leu-Gln-AFC (Abu = Aminobutyrate; Tle = t-Butylglycine; AFC= 7-amino-4-trifluoromethyl coumarin) is a kinetically preferred fluorogenic substrate for the detection of SARS-CoV and SARS-CoV-2 main protease (Mpro; 3CLpro) activity. Mpro cleavage results in the release of the C-terminal AFC and increased fluorescence (ex 380+/-20 nm, em 500+/-20 nm).
