Figure 4. Neutralizing antibody titers in sera of mice vaccinated with L2R4 proteins.

Figure 4

Mice were immunized and sera were collected (see Figure 3 legend for detail). Antisera were tested for in vitro neutralization titers against HPV16 (A), HPV18 (B), HPV45 (C), HPV52 (D), HPV58 (E), HPV6 (F), HPV11 (G) and HPV5 (H) pseudovirus. The horizontal bars represent the geometric mean antibody titers. The statistically significant differences (using one-way ANOVA and Bonferroni multiple comparison test) were indicated by: *, P<0.05; **, P<0.01; ***, P<0.001. ND, not detectable.
