Immuno-localization of PfSEP14 on synchronous P. falciparum cultures. Double immunofluorescence assay was performed on unfixed parasites with PfSEP14-specific rat immune serum (dilution 1:200), revealed with FITC-conjugated anti-rat IgG (green) and with anti-Pf332 monoclonal antibody Mab51-22, revealed with TRITC-conjugated anti-mouse IgG (red). Parasite nuclei are stained with DAPI. Bar represents 5mm. At the stage of ring the distribution of PfSEP14 did not co-localize with that obtained with Mab51-22 which, at this stage, cross reacts with RESA. A similar pattern of fluorescence for both antigens appeared instead in trophozoites, while at the schizont stage patterns were distinguishable, in that SEP14-associated fluorescence was diffuse within the parasitized cell and did not appear concentrated at the edges of the schizonts.
