PF3D7_0202000 knob-associated histidine-rich protein

(A) live cell fluorescence microscopy of 3D7-KAHRP-GFP. Panels are GFP fluorescence, bright field (BF) and a merge of the two. Scale bar: 5 μm. KAHRP-GFP was trafficked to the RBC membrane and gave a rim fluorescence pattern (B) Immunofluorescence microscopy of acetone-fixed RBCs infected with 3D7-KAHRP-GFP, SBP1 is a marker for the Maurer’s clefts.

Lower row: Immunofluorescence microscopy of acetone fixed RBCs infected with wild type. Smears were probed with mouse anti-PfEMP3 (green) and rabbit anti-SBP1 (red). A characteristic PfEMP3 profile at the RBC membrane is seen.
