Fig. 8. Immunolocalization of Nowa protein in the late growth phase of nematocyst morphogenesis. Confocal microscopy of three nematocysts with an outer tubule. (A) Surface projection of mAb H22 (green) and spinalin antibody staining (red). A' shows mAb H22 staining only to visualize staining of the outer tubule. (B) Schematic representation of a nematocyst with an outer tubule. Bars, 5 µm.
