Establishment and Evaluation of Stable Cell Lines Inhibiting Foot-and-Mouth Disease Virus by RNA Interference

Figure 3

The results of the immunofluorescence assay for the cells transfected with the recombinant vectors at the thirtieth passage. The FMDV immune mouse ascites (1 : 1000) and a secondary goat-anti-mouse IgG antibody (1 : 100) conjugated with fluorescein isothiocyanate (FITC) were used to detect the viral protein. The specific fluorescence intensity under different recombinant vectors’ treatments was lower than that of the mock and the negative control (pshRNA) at different levels.
