Biochem/physiol Actions

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.

First identified in The Netherlands in 2004, human coronavirus NL63 (HCoV-NL63) was found to cause worldwide infections. Patients infected by HCoV-NL63 are typically young children with upper and lower respiratory tract infection, presenting with symptoms including croup, bronchiolitis, and pneumonia.
