Blocking of DEN-2 virus binding by specific antibodies. C6/36 cell monolayers were incubated with 1:10 or 1:1000 diluted pre-immune serum (PI), anti-EP, anti-R67, anti-R80 or anti-MG. To assay the binding of radiolabeled virus, cells were dissolved in 3% SDS in all experiments. The total [125I]DENV2 virus bound was 5,286 ± 300 cpm. The experiments were repeated at least 3 times in quadruplicate.
