PfAEP localization in schizont stages analyzed by confocal microscopy. Subcellular localization of PfAEP was studied by co-staining with antibodies against micronemal protein EBA-175 (B), rhoptry bulb protein PTRAMP (C), and rhoptry neck,
apical asparagine rich protein (AARP) (D), apical rhoptry neck protein (ARNP) (E), and merozoite surface protein (MSP) (F).As a control, pre-immune serum of PfAEP was checked and no staining was observed in schizonts (A). Mature schizonts were costained with anti-PfAEP (green) and anti-EBA-175, TRAMP, AARP, ARNP, MSP-119 antibodies (red). The nuclei of schizonts were stained with DAPI (blue) and visualized by Nikon N-SIM confocal microscope. All apical marker proteins and PfAEP showed punctate staining in schizonts distinct from DAPI. Co-staining of PfAEP with surface marker MSP-119 showed PfARNP localized at the apical tip with surface of merozoites stained by MSP-119. PfAEP staining did not merge with either markers of microneme or rhoptry indicating that PfAEP is neither a resident of micronemes or rhoptry of
merozoites. Scale bar 2 mm.
