Figure 1. Priming with al-UV-DENV2 induces non-neutralizing DENV-specific IgG.
AG129 mice were primed with al-UV-DENV2 on days −14 and −5. On day −1, DENV-specific IgG levels were measured in the serum by ELISA (A) and the presence of neutralizing Abs was detected by PRNT50 (B).
Results were pooled from 2 independent experiments, n=9–10 total per group. The dotted line represents the background signal in A, and the detection limit in B. For B: each symbol represents one mouse, and the DENV-neutralizing Ab 4G2 was used as a positive control. Samples under the detection limit are represented in grey.
