rPfMSP2-associated fibrils mask relevant PfMSP2-specific epitopes. Competition ELISAs were conducted using a fixed concentration of rabbit antibody induced by (A) rPfMSP2 or (B) rPfMSP2/8 immunization. Sera were co-incubated in solution with increasing amounts of rPfMSP2 or rPfMSP2/8. Residual binding to plate-bound immunizing antigen for each antigen + antibody cocktail was measured in duplicate by ELISA and calculated as (A405 of IgG with inhibitor/A405 without inhibitor) × 100. Statistical significance was conducted at maximum levels of inhibition. Data from samples within an immunization group were averaged and compared. Asterisk indicates significance (Mann-Whitney U test, p < 0.03; ns, not significant).
