The PfRON4 and PfRON5 proteins localize to the rhoptry neck. A, Antibodies raised against PfRON4 and PfRON5 recognize specific protein products in schizont parasite extracts. B, IFAs using the anti-PfRON antibodies reveal staining of the apical tip of free merozoite, in close apposition with the rhoptry bulb markers PfRAP1 and PfRAMA, suggesting a rhoptry neck localization. Scale bar: 0.2μm C, Immunoelectron microscopy confirms that PfRON 4 localizes to the rhoptry neck. Scale bar: 0.1μm
