FIG. 7.

Effect of HN expression on viral replication. The cell lines were infected with HPF3, and plaque assays were used to assess the amount of infectious particles released by the different cell lines after infection. Cell clones and control 293T cells were infected with HPF3 at an MOI of 0.1. At 24h after infection, supernatants from each cell line were collected, plaqued on monolayers of CV1 cells, and immunostained. Each column is the mean of results of three different experiments done in triplicate. The bars denote the standard deviation.
