FIG 6.
Reactivity of PvDBP-specific IgG with recombinant PfEMP1 proteins. Shown are ELISA reactivities of PvDBP-specific human (DBL10) and mouse (3D10) monoclonal antibodies (mAb) (A, C, and E) and PvDBP-specific rabbit antiserum (B, D, and F) with the recombinant full-length PfEMP1 proteins FV2BIC (A and B), FV2CHO (C and D), and FV6BIC (E and F). (A, C, and E) Reactivities of irrelevant (Ebola virus-specific) human monoclonal IgG (EBL040), mouse polyclonal IgG, as well as the VAR2CSA-type PfEMP1-specific human monoclonal antibody PAM1.4. (B, D, and F) IgG reactivities in human plasma pools from unexposed Colombians, infected pregnant Colombians, exposed Ghanaian women, unexposed Danish adults, and preimmune rabbit serum are shown for comparison. Serial 2-fold dilution series are shown for all antibody reagents.
