Figure 5From: Development of a reverse genetics system for respiratory syncytial virus long strain and an immunogenicity study of the recombinant virusGrowth of (recombinant) viruses in Hep-2 cell lines. Growth characteristic of RSV long strain and two recovered viruses rLong and rLong-∆G-EGFP in Hep-2 monolayers. viruses were harvested at the indicated time points and virus PFU titers were determined, Each value is the mean titer of two wells at indicated time points.Back to article page
