Immunofluorescence analysis of schizonts, segmenter, and released merozoites of P. falciparum using anti-D13 MAb DD1.1 and confocal microscopy. In column I, staining with MAb DD1.1 is shown, while in column II the phase contrast of the corresponding parasites is presented. Specific staining of schizonts (first row), segmenters (second row) and released merozoites (third row) are presented. Interestingly, in the merozoite stage, D13 protein seemed to be concentrated in a distinct area of the cell, while during schizont stages the protein was more evenly distributed in the parasite.
