*DENV, dengue virus; IC50, 50% inhibitory concentration; ID, identification.
†All neutralization testing performed on Vero cells with the exception of DT003, which was limiting and historic values performed on a U937 Flow-based assay are shown for DENV-1–4. Zika virus IC50 values for DT003 are from Vero assays.
‡Curves that did not pass quality metrics are marked. Such curves might signify very low titer IC50 values or variable background at the lower limit of detection in serum with no specific neutralization activity.
