Characterization of rRSV-EGFP. (a) Identification of the rescued rRSV-EGFP by RT-PCR. M, DNA Ladder DL2000; control of HEp-2 cells (1), wtRSV Long infected HEp-2 cells (2), or rRSV-EGFP infected HEp-2 cells (3). (b) The replication titers of rRSV-EGFP during serial blind passages from p1 to p9 by immunoplaque assay. (c) The growth kinetic of rRSV-EGFP. The growth curve for rRSV-EGFP was compared with those for wtRSV Long, rRSV-RFP, and rRSV-Luc. Each virus was harvested every other 24 h postinfection and titers were assayed by immunoplaque assay. (d) The replication capacity of the rRSV-EGFP in HEp-2, Vero, or 293T cells. Viruses were harvested at 48 h postinfection and titers were determined by assays of immunoplaque and RT-qPCR. Data were shown as mean ± SD. , .
