  1. 1Percent of wild-type (WT) DENV-2 VLP reactivity for MAbs exhibiting varying levels of cross-reactivity (CR) and selected from different flaviviruses.
  2. 2 MHIAF is polyclonal murine ascitic fluid; group CR antibodies recognize all viruses of the four major pathogenic flavivirus serocomplexes; sub-group CR MAbs recognize all or some members of two or more different flavivirus serocomplexes (e.g., MAbs 20, 5–1 and 5–2 recognize DENV-2 and JEV, JEV and DENV-2 and JEV, DENV-1 and −2 respectively); comp. and sub-comp. CR MAbs recognize all four DENV complex viruses or a subset thereof respectively, and type-specific MAbs recognize only DENV-2.
  3. 3 MAb reactivities for wild-type (WT) DENV-2 VLP are presented as inverse log10 antigen-capture ELISA endpoint values and all mutant VLPs as percent of remaining reactivity compared to WT.
  4. 4 nd denotes not determined.
  5. 5Mutant VLPs containing amino acid substitutions in the EDIIFP G106R/L107D (RD), in EDIII K310E/E311R/P364R (ERR), or in both the EDIIFP and EDIII G106R/L107D/K310E/E311R/P364R (RDERR).
