Figure 1 ELISAs were performed against MR766 ZIKV supernatant to assess binding activities.
ELISAs were performed as duplicates, and results are reported as values of the area under the concentration-time curve (AUC). Error bars represent standard errors of the means (SEM).

Figure 6 Vero cells were infected with MR766 ZIKV and used as targets for measuring Fc-FcγR effector functions with a genetically modified Jurkat cell line expressing human FcγRIIIa with an inducible luciferase reporter gene.
Fold induction was measured in relative light units, and results were compared to infected cells with no antibody added. Error bars represent standard error of the means (SEM).

Figure 7 To examine whether enhancement of flavivirus infection in vitro is observed, monoclonal antibodies were incubated with ZIKV and added to FcγR-bearing K562 cells.
All monoclonal antibodies were tested at a starting concentration of 3.3 μg per ml and serially diluted 4-fold. Both assays were run in duplicate, and fold induction was measured as the percentage of infected cells as determined by flow cytometry divided by the percentage of infected cells with no antibody added (virus alone).

Figure 8 Neutralization occurs at a binding step.
Analysis of the timing of antibody neutralization activity was performed. The results for synchronized infections of Vero cells with wild-type or S368R MR766 virus are shown. Vero cells were equilibrated to 4°C at −3 h, and virus plus antibody or virus alone was added to the cells. At 0 h Vero cells were washed twice with PBS, warm medium was added with the relevant antibody, and cells were moved to 37°C. For each assay, results are normalized to those of infections performed without any antibody added. Antibody was added at a concentration of 10 IC50s as determined by plaque reduction neutralization test. Infection was measured by 4G2 anti-envelope staining at 48 h postinfection.
