Figure 5From: Acetylation at K108 of the NS1 protein is important for the replication and virulence of influenza virusLocalization of NS1 proteins in infected MDCK cells. The MDCK cells were infected with WSN-NS1-108R, WSN-NS1-108Q, or WSN-wt. The cells were fixed, permeabilized at 12 (A), 24 (B), and 36 (C) hours post-infection and probed with an anti-NS1 antibody, followed by DAPI staining. NS1 (green) and nuclei (blue) were visualized by confocal microscopy.Back to article page
