NA inhibition assay. The NA activity of influenza virus PR8 and rgPR8(H275Y) was measured in the presence of increasing concentrations of PC8 (a) or OSV-C (b). After addition of the NA-Fluor fluorescent substrate, enzymatic activity was measured by reading the fluorescence intensity with excitation at 350 nm and emission at 450 nm. The data shown are the means ± S.D. of three different samples
