Upper panel: Immunofluorescence analysis (IFA) of paraformaldehyde-fixed gametocyte infected erythroblast at 6 dpi stained with anti-Pf11-1 antibodies (green) and with anti-glycophorin A (GPA) labelling the erythroblast membrane. the gametocyte-specific protein Pf11-1 was detected both in the parasite and in the infected erythroblast. Lower panel: Infection with the Hsp70-GFP line (upper panels) and with the Pfs16-GFP line (lower panels) were observed by fluorescent microscopy at 2 dpi (upper panels and lower left panel) and 6 dpi (lower right panel). Erythroblast membrane is stained with PKH-26 (red). Hsp70-GFP line expressing GFP throughout the entire parasite life cycle under the control of the constitutive promoter hsp70 to monitor total parasitemia, and the Pfs16-GFP line expressing GFP under the control of the gametocyte-specific promoter Pfs16 to monitor gametocytemia.
