Localization of Pfstomatin and RhopH2 to the PVM in ring-infected erythrocytes (0–8 h post-invasion). Cells were subjected to a standard indirect immunofluorescence assay where samples were permeabilized with saponin and probed with antibodies to: Pfstomatin (Ai; green), RhopH2 (Bi; green), and the PVM marker EXP-1 (Aii and Bii; red); the merged images are shown in Aiii and Biii. In C and D, ring-infected erythrocytes were treated with tetanolysin and incubated with antibodies to: Pfstomatin (Ci; red), RhopH2 (Di; red) and the PPM marker MSP-1 (Cii and Dii; green); the merged images are shown in Ciii and Diii. In E and F, rings treated with tetanolysin and permeabilized with saponin were incubated with antibodies to: Pfstomatin (Ei; red), RhopH2 (Fi; red), and MSP-1 (Eii and Fii; green); the merged images are shown in Diii and Fiii. All images shown are single optical section. The nucleus (blue) was stained with Hoechst 33342. Scale bars represent 2 mm.
