High resolution view of the bundles of microtubules that arise from along the elaborately woven blanket of the filamentous reticulum that covers the ribbed wall of the right side of the buccal cavity....

High resolution image of the dividing macronucleus shows it may be porous to microtubules. Segments of microtubules are found both outside and inside the nuclear envelope in this figure although one c...

In mitosis the nuclear envelope of the micronucleus becomes heavily and uniformly labeled with anti-b-tubulin which is not in the form of microtubules. Some tubulin is also present inside the micronuc...

High resolution image of the macronucleus which contains microtubules that lie inside a seemingly intact nuclear envelope. Microtubules orient along the axis of macronuclear elongation in the form of ...

Immunogold b-tubulin labeled ribbons that extend from the cytopharynx and have discoidal vesicles bound to their kinetic side, i.e., their anterior side relative to the cell’s longitudinal axis (sid...

Immunogold labeled microtubules next to the cytoproct radiate from basal bodies and also from the tip of the cytoproct. These microtubules lie along the approaching spent DV. b-tubulin immunogold labe...

The radial arms of the Contractile Vacuole Complex or CVC each contain a collecting canal enclosed by a microtubular ribbon split lengthwise into several smaller ribbons, a meshwork of smooth spongiom...

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...

High resolution image of the b-tubulin immunogold labeled microtubules that arise from the apex of the cytoproct ridge and pass to the spent DV membrane. Trichocyst and trichocyst tip included in this...

High resolution image of the surface pattern of P. tetraurelia in a region with two basal bodies in each cortical unit. This is a thin-frozen section labeled with immunogold showing the location of b-...
