Figure 2From: Neuraminidase activity provides a practical read-out for a high throughput influenza antiviral screening assayNA activity in cell culture wells and in the supernatants of cells infected 20 hr earlier in the presence of different amounts of zanamivir. In this experiment, MDCK cells were infected with 400 TCID50 A/Memphis/14/98 (MOI = 0.01). The inoculated amount of virus is not sufficient to measure NA activity at the selected conditions.Back to article page
