Immunolocalization of c-myc epitope-tagged PFE1605w PHIST protein within infected erythrocytes. A) Synchronized parasites were harvested at different time points after Percoll-sorbitol purification, air-dried and fixed with ice-cold methanol. Epitope-tagged proteins were stained with anti-c-myc monoclonal antibodies that were conjugated with FITC. Nuclei were stained with DAPI (blue). The abbreviations used to describe parasite stages are as follows: 22 h, late ring stage; 30 h, early-trophozoite stage; 42 h, mid-trophozoite stage; 48 h, late trophozoite stage; and schizont stage. B) Co-localization was assayed using rabbit polyclonal SBP1 followed by goat anti-rabbit IgG conjugated with Alexa 594 (red). C) The pattern of expression of c-myc epitope tagged PFE1605w PHIST protein is dependent on the fixation protocol. When infected erythrocytes are fixed in solution with 1% paraformaldehyde, 0.075% glutaraldehyde, then PHIST protein shows a broader punctate expression than the Maurer’s cleft marker, SPB1.
