Fig. 4. Bivalent CSP and Pfs230D1+ immunization of outbred mice.

Fig. 4

ICR mice were immunized with CSP, Pfs230D1+ or bivalent antigens with CoPoP liposomes or alum on day 0 and day 21, final bleeding were collected on day 42. a Anti CSP ELISA units (EU) and (b) Anti Pfs230D1+ EU. ELISA experiments were performed with n = 10 mice. For A and B, bars represent geometric mean, and one-way ANOVA followed by Tukey test using log-transformed data were used to compared difference among CSP/CP, CSP/230/CP, CSP/Alum and CSP/230D1/Alum for a and 230/CP, CSP/230/CP, 230/Alum and CSP/230/Alum for b. ****p < 0.0001, ***p < 0.001, **p < 0.005. c Standard membrane feeding assay (SMFA) results of purified IgGs tested at 750 μg/ml with complement. %TRA and the 95% confidence interval (95% CI) are shown. d Immunofluorescence assay of fixed NF54 parasites at sporozoite and gametocyte stages. Bar: 10 µm. Image was taken from a single experiment. Red symbols or outlines indicate bivalent, liposome-displayed CSP/230.
