Microneutralization assay results. The virus/antiserum mixtures were added into RD cells and incubated at 37°C. After 7 days, the cells were observed to evaluate the appearance of cytopathic effects (CPEs). (A) Uninfected cells. (B) EV71-bound cells were treated with the anti-HBc-N149-VP4N20 sera. (C) EV71-infected cells. (D) EV71-bound cells were treated with the anti-HBc-N149 sera.
