MAEBL localized with rhoptry proteins and on the merozoite surface and not with microneme proteins. Dual-label indirect immunofluorescence assays analyzed by scanning confocal laser microscopy are shown in each row of images, using primary antibodies against a rhoptry and microneme protein. In each row, the immunolocalization pattern for the first protein listed is in green in the first left-hand panel and the second protein listed is the second panel shown in red. The third panel is the merged image of the first two panels, the final right-hand panel is the brightfield image. Color was assigned electronically.

Phase contrast photograph of P. falciparum schizonts and free merozoites (100x) showing the reactivity of the mouse polyclonal anti-r-PfM2. (B) IFA reactivity of the mouse anti-r-PfM2 serum with methanol fixed late stage schizonts and free merozoites of P. falciparum 3D7 clone (100x). (C) IFA reactivity to air dried P. falciparum sporozoites (100x) using mouse anti-r-PfM2 antibody. Apical punctate fluorescence was observed in free merozoites and in late-stage schizonts. Positive fluorescence was also recorded on the surface of anopheles salivary gland sporozoites.Ghai M, Dutta S, Hall T, Freilich D, Ockenhouse CF.
