Fig. 4. Full-length gH/gL elicits higher neutralizing titers than multimeric gH/gL ectodomain constructs when delivered by LION/repRNA.

Fig. 4

a Reciprocal endpoint gH/gL binding titers from mice immunized with LION/repRNA encoding gH/gL 4-mer, gH/gL 7-mer and gH/gL 60-mer were measured by ELISA. Titers from two immunizations with 10 μg full-length gH/gL (from Fig. 2) are included for comparison as indicated. EBV neutralizing titers in the serum from the mice in (a) were measured in epithelial (b) and B cell (c) infection assays. Each dot represents the average of three technical replicates for an individual mouse at each timepoint (n = 5 per group in multimer construct vaccinations, n = 8 for full-length gH/gL) and the lines connect the means. The arrows indicate the time of immunization. See Table S2 for statistical comparisons.
