Confocal fluorescence microscopy images of schizont stage transfected 3D7 P. falciparum-infected RBCs expressing a GFP chimera directed to the parasite plasma membrane. DIC image, the GFP fluorescence signal and an overlay of a P. falciparum 92 cysteine-rich surface protein-GFP transfectant. Scale bar = 5 µm. Pf92 localizes to the merozoite surface and is a putative GPI-anchored protein distributed evenly over the parasite surface.

Localization of Pf92 fused to a GFP reporter and expressed in an inducible system that allows strong surface expression. Pf92-GFP was mostly concentrated essentially on the surface of merozoite.

Fixed and blocked late schizonts and ring stages were incubated with rabbit anti-Pf92 immune sera (B-I) or with Pf113 immune rabbit sera (J-M). In late schizonts Pf92 localized in merozoite and in ring stages (C-E). Pf113 was only detected on the merozoite surface, and not in other subcellular compartments or in any other intraerythrocytic lifecycle stage.Obando-Martinez AZ, Curtidor H, Arévalo-Pinzón G, Vanegas M, Vizcaino C, Patarroyo MA, Patarroyo ME.
