Biochem/physiol Actions

FRET substrate suitable to measure protease activity of COVID-19 virus Mpro, SARS-CoV Mpro, and some other viruses
MCA-AVLQSGFR-Lys(Dnp)-Lys-NH2 is a fluorescence resonance energy transfer (FRET) substrate derived from the N-terminal auto-cleavage fragment of the SARS-CoV Mpro viral protease ((excitation wavelengths 320 nm and emission wavelengths 405 nm). MCA-AVLQSGFR-Lys(Dnp)-Lys-NH2 is suitable to measure protease activity of COVID-19 virus Mpro, SARS-CoV Mpro, and other viruses.
