Protection of Vero cells from PEDV destruction by shRNAs. Vero cells were transfected with plasmids as indicated and then infected with PEDV at 100 TCID₅₀. At 40 h post-infection including 4 h incubation along with MTS, viable cell numbers were evaluated by a MTS assay. OD values represent the mean ± SD of three separate experiments performed in triplicate (a). The cell viability was calculated using the MTS assay at 40 h post-infection (b)
