Figure 2From: Development of a reverse genetics system for respiratory syncytial virus long strain and an immunogenicity study of the recombinant virusIdentification of recovered recombinant viruses by fluorescent assay and plaque assay. (A) the successfully recovery of rLong was confirmed through indirect immune fluorescent assay by immune-staining with an anti-RSV G1 polyclonal antibody targeting G protein epitopes as the first antibody. (B) the recovery of rLong-∆G-EGFP was evaluated by observating under fluorescent microscope. (C) the negative control was Hep-2 cells without infected by viruses. (D-F) Plaque morphology for wild-type RSV long virus, rLong and rLong-∆G-EGFP respectively.Back to article page
