Inhibition of EV71 infectivity at the pre- and post-attachment stages by neutralizing antibodies. At the end of the incubation period, the cells were examined for the cytopathic effect. In addition, cell viability was determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay, and the percentage of neutralization for each treatment was calculated. The data are the mean ± standard error of the mean from two independent experiments. EC 50 50% effective concentration
