An immunofluorescence assay was performed on late-schizont-stage W2mef parasites stained for RH2a using the anti-RH2a MAb C22 and costained either with an antibody against the rhoptry neck marker RH1 (A), rabbit polyclonal antibody R2A9, recognizing both RH2a and RH2b (B), or an antibody against the micronemal marker AMA1 (C) or EBA175 (D). Bars, 5 mm. PfRH2a showed a punctate pattern at the apical tip of the merozoite in schizonts and appeared to colocalize with PfRH1 in W2mef and 3D7 parasites, strongly suggesting that RH2a is located at the rhoptry neck.
