Specificity of IgG antibody in mice immunized with Plasmodium vivax circumsporozoite protein (CSP) recombinants. (A) Schematic representation of recombinant proteins used as a substrate bound to the plates in the ELISA assay. (B) C57BL/6 mice were immunized s.c. with the purified proteins in the presence of the adjuvant Poly(I:C) according to the timeline described in Figure 3A. The specificity of IgG antibody serum titers toward rFliC, FliC-PvCSP-repeats and No repeats proteins were analyzed by ELISA in sera of mice from groups 2 to 6 described in Figure 3B. The results are expressed as mean ± SD (n = 6 animals/group). P values are indicated. Differences were considered statistically significant when P < 0.05.
