A micrograph of Tetrahymena showing a transverse ribbon starting from the anterior right side of the proximal end of a basal body (out of section plane) and crossing under the pellicle to end under th...

Monoclonal antibody for antigen B2 (called mAb PC-1 in Fok et al., Eur. J. Cell Biol. 40:1-8, 1986) is located on the cytopharynx and along the cytopharyngeal ribbons. It can be seen here on the DV-I ...

Immunogold label specific for Q2 antigen on discoidal vesicles. The same mAb used in CIL:36721 heavily labels discoidal vesicles and less heavily the cytopharyngeal membrane. A few gold particles are ...

High resolution image of microtubules that sometimes extend deep into the cytosol from the basal bodies. They serve to guide the trichocysts to their docking sites at the plasma membrane (see Plattner...

A high resolution view of the radial arm of the Contractile Vacuole Complex or CVC each contain a collecting canal enclosed by a microtubular ribbon split lengthwise into several smaller ribbons, a me...

Monoclonal antibody for antigen B2 (called mAb PC-1 in Fok et al., Eur. J. Cell Biol. 40:1-8, 1986) is located on the cytopharynx and along the cytopharyngeal ribbons. It can be seen here on the DV-I ...

Monoclonal antibody, E30-2-1, was raised to antigen D6 that specifically labels acidosomes and DV-II. There was no label on the nascent vacuole membrane or ciliary membranes. This cell had been incuba...

Quadrulus membranelle (4 rows of cilia) in the buccal cavity of Paramecium tetraurelia. Microtubules of the axonemes of the cilia and the triplet fibers of the basal bodies are labeled. Ribbons of mic...

Bundles of microtubules arise from along the elaborately woven blanket of the filamentous reticulum that covers the ribbed wall of the right side of the buccal cavity. A bundle forms beneath the botto...

b-tubulin immunogold labeled microtubules arise from the apex of the cytoproct ridge and pass to the spent DV membrane. Trichocyst and trichocyst tip included in this image. TEM taken on 7/5/96 by R. ...
