Bz-Nle-Lys-Arg-Arg-AMC

This fluorescent tetrapeptide substrate (Bz-Nle-Lys-Arg-Arg-AMC) enables the quantitative detection of NS3 protease activity from flaviviruses like Dengue, Zika, and Yellow Fever. The cleavage releases AMC, which is monitored fluorometrically (Ex/Em ~350/450 nm), making it suitable for high-throughput inhibitor screening in antiviral drug discovery research.
