bNon-neutralizing EV71 mAbs, 17-1-10B and 16-2-1A, and post-infection serum collected at day 9 after illness onset from a hospitalized child with laboratory-confirmed genotype B5 EV71 infection were included in the test. The neutralizing activity of each representative mAb is defined as the lowest antibody concentration that completely inhibited CPE formation. Each sample dilution was assayed in triplicate, and the assay was carried out twice with equivalent results
