PfRH2b is associated with the moving junction during merozoite invasion. The process of merozoite invasion was closely monitored to locate the position of PfRH2b of burst schizont, free merozoites, random merozoite attachment, apposed merozoite and penetrating merozoite. (A) Merozoites were stained for MSP1 (MSP1, green) and PfRH2 (PfRH2, red). PfRH2 apical punctuate staining was observed in the free and attaching merozoites while in invading merozoites two punctuate staining were observed at the anchorage of the moving junction. The presence of PfRH2b (PfRH2b, red) at the moving junction was further confirmed

with EBA175 (B, green). Merozoites of focus are shown with red circles. In the merged images, areas of overlap between the red and the green signals are shown in yellow. DAPI (blue) stained for nuclei.
