PF3D7_0935800 cytoadherence linked asexual protein 9

VAR2CSA and CLAG9 are present in the IRBC membranes of C4S-adherent parasites. The C4S-adherent FCR3 parasites, at the late ring to early trophozoite stages, were analyzed by immunoelectron microscopy by using rat anti-VAR2CSA and rabbit anti-CLAG9 primary antibodies followed by biotin-conjugated goat anti-rat IgG and 18-nm gold particle-conjugated goat anti-rabbit IgG secondary antibodies. The bound biotin-labeled antibodies were probed with 12-nm gold particles conjugated streptavidin. Arrows and arrowheads indicate, respectively, 12-and 18-nm gold particles. (Scale bars: 200 nm.) a substantial level of CLAG9 is located mainly at or in close proximity of the IRBC membrane in association with VAR2CSA.
