Plasmodium vivax Duffy binding protein (PvDBP) monoclonal antibody (mAb) 3D10 recognizes live Plasmodium falciparum strain CS2–infected red blood cells (RBCs). CS2, a placental isolate, and NF54–chondroitin sulfate A (CSA) infected RBCs were analyzed by flow cytometry. A and B, To verify the expression of VAR2CSA, infected RBCs were stained with normal rabbit serum (A) and a polyclonal anti-VAR2CSA rabbit antibody (B), both at a 1:40 dilution. C and D, All 3 strains were stained with the immunoglobulin G1 (IgG1) isotype control (C) and PvDBP 3D10 mAb (D), both at 143 μg/mL. The percentage of infected RBCs recognized by the antibody is indicated on each plot.
