description

SARS-CoV-2 main protease Mpro (3CLpro) represents a major target in drug development against COVID-19. Prior to cleavage, rhodamine is bound to glutamine and thus not fluorescent. Upon cleavage, the fluorophore becomes active. This rhodamine 110 based Mpro substrate has a red-shifted excitation (492 nm) and emission (529) compared to the FRET substrate LS-4180. It shows a better signal-to-noise ratio and produces less interference with potential inhibitors in screening assays. This leads to a higher sensitivity compared to the Dabcyl/Edans substrate. In consequence, lower substrate amounts are required for successful assays. Dissolve in dry DMSO and use as aliquots.
