PF3D7_0202000 knob-associated histidine-rich protein

c Immunofluorescence microscopy of sexually induced PfGEXP5-GFP transfectants (14 h pi), probed with rabbit anti-GFP (green) and mouse anti-Pfs16 (red) antibodies. PfGEXP5-GFP is expressed and exported to the host cell cytoplasm in Pfs16-positive cells (c) d Immuno-fluorescence microscopy of sexually induced PfGEXP5-GFP transfectants (14 h pi, top) and an asexual trophozoite from the same line (bottom), probed with anti-GFP (green) and anti-KAHRP (red) antibodies. Scale bars 3 μm. PfGEXP5-GFP positive cells did not exhibit KAHRP labelling at the RBC surface, while KAHRP-positive cells (i.e., asexual stages) were negative for exported PfGEXP5-GFP (d).
