Figure 6: Neutralization of RSV on Hep-2 cells, ELISA. The number of RSV mixed with different dilutions of serum (1 : 16 and 1 : 8) from mice groups (PBS, RSV, infected and PF DNA-administrated mice) reduced significantly. ELISA was used to detect RSV reduction. Two sera pools from each group of mice were run in duplicate. Bar graphs are represented as means with standard deviations. Significantly different () from PBS group; significantly different () from PBS and PF DNA groups. values () were calculated using ANOVA, Tukey’s test.
