Fig. 4From: Genetic variations on 31 and 450 residues of influenza A nucleoprotein affect viral replication and translationVariations on NP-31 and NP-450 residues affected viral growth kinetics. A549 cells were infected with reverse genetics with different amino acid composition as indicated at (a) MOI of 1 and (b)(c) MOI of 0.01 at 37 °C. At the selected time points, viruses were harvested and examined by plaque assay in MDCK cells. The one-way ANOVA with Tukey post-test was performed; *p < 0.05, **p < 0.01, ***p < 0.001Back to article page
