Figure 4. The antiviral activities of the SP40 peptide in various cell lines.

Vero, HeLa and HT-29 cell lines were pre-treated with the SP40 peptide at various concentrations for 1 hour at room temperature before infection with EV-71 at a MOI of 0.1. (A) The viral induced cytopathic effects in various cell lines were observed 24-hour post-infection. (B) The viral RNA inhibition that were quantitated by RT TaqMan real-time PCR assay.
