Fig. 7. Association of the bi-lobe with the FAZ. Fixed cells were labeled with L3B2 for FAZ (red), anti-TbCentrin4 for bi-lobe (filled arrowheads; green) and basal bodies (open arrowheads; green), and DAPI for nucleus and kinetoplast (blue). At all stages of the cell cycle, the posterior tip of the FAZ overlapped with the bi-lobe, in particular the anterior lobe (large filled arrowheads). Scale bar, 5 µm.
