Localization of PfMRP1 within the asexual stages of P. falciparum. In column 1 blue (DAPI) shows the nuclear staining. In column 2 red shows PfMRP1 staining. In column 3 green shows glycophorin A (A, B, and C) or PfERC (D and E) staining. Column 4 shows the merge of column 1–3. Finally, column 5 shows the differential interference contrast image. Represented in rows: A, rings; B, early schizont; C, schizont; D, trophozoite; E, schizont and ring. The arrow indicates the food vacuole.
