PF3D7_1252100 rhoptry neck protein 3

The expression and localization of PfRON3 in Plasmodium falciparum merozoites. (B) PfRON3 is expressed inside Plasmodium merozoites. Schizont stage parasites were dual-labeled with PfRON3-specific antibodies in combination with MSP1-42 antibodies. Nuclei are stained with DAPI. MSP1-42 protein was located at the merozoite membrane (red fluorescence) and RON3 was located inside merozoites (green fluorescence). (C) PfRON3 location shown via immunoelectronic microscopy. The section of merozoite in mature schizonts was labeled with purified rabbit anti-PfRON3 antibodies and subsequently detected with a secondary antibody conjugated with gold particles (arrow-headed). The black dots indicate signals from gold particles localized in the rhoptry body. Bar represents 200 nm.
