PF3D7_0501200 parasite-infected erythrocyte surface protein

Localization of PIESP1 and PIESP2 with specific antibodies. (A) Immunofluorescent microscopy of PIEs (P. falciparum strain 3D7) fixed onto glass slides. Glass slide were incubated with anti-PIESP1 (Plates a and b), anti-PIESP2 (Plates c and d), and pooled preimmune sera (Plates e and f). Fluorescent images (Plates a, c, and e) and phase-contrast images (Plates b, d, and f) were collected simultaneously on an Olympus BX-60. (B) Localization of PIESPs with immunofluorescent confocal microscopy. Live P. falciparum strains 3D7 and Malayan Camp (unselected for knob and rosetting phenotypes) were incubated in suspension with specified antibodies. Plates a–d, anti-PIESP1 as primary antibody; Plates e–h, anti-PIESP2 as primary antibody; Plates i–l, preimmune sera as primary antibody. The 488 and 568 nm laser channels, for Alexa Fluor 488 and ethidine bromide, respectively, were collected separately and later superimposed (Plates a, c, e, g, i, and k). The DIC images (Plates b, d, f, h, j, and l) were collected simultaneously using the transmitted light detector.
