VAR3 on the surface ofPlasmodium falciparuminfected erythrocytes. Reactivity with anti-VAR3 antibodies of live P. falciparum 3D7 and IT/FCR3 before and after antibody selection with a rabbit antiserum against recombinant DBLα/ζ-DBLε of PFI1820w shown as (a) number of events/P. falciparum-infected erythrocytes vs. FITC flourescence intensity by flow cytometry, (b) DIC shadow-cast image with the fluorescence image superimposed and (c) the fluorescence image alone on serorepresentative infected erythrocytes in confocal microscopy. Scale bar 5 μM.
