FIG 2.

Antibody recognition of P. vivax CSP recombinant proteins. ELISAs were performed with each of the four PvCSP recombinant (Rec.) proteins bound to the plates to determine whether the polypeptides retained the epitopes recognized by specific MAbs generated against radiation-attenuated P. vivax sporozoites. (A) MAb against the His tag. (B) MAb 2F2 specific to the allelic form PvCSP-VK210. (C) MAb 2E10.E9 specific to the allelic form PvCSP-VK247. (D) Polyclonal antibodies to the PvCSP-Vivax-like repeat region.
