The postoral fibers are also heavily labeled by anti-b-tubulin. The cell was lightly fixed, placed in metylcellulose and frozen in liquid nitrogen. Sections were produced at -100°C before thawing and...

Mucocysts have a herringbone pattern of subunits and are surrounded by a membrane that fuses with the plasma membrane. When the mucocyst content is extruded the content expands (see Hausmann, Protisto...

The cytopharyngeal ribbons of microtubules tend to curve into a “C” shape away from the cytopharynx but they still remain connected as a ribbon and are heavily labeled by immunogold when exposed t...

A cross section near the proximal end of the cilium. Triangular densities link the doublets to the membrane. Bar = 0.2µm. TEM taken 7/23/65 by R. Allen with RCA EMU3F operating at 50kV. Adapted with ...

A view of the left side of the buccal cavity. It is covered by the plasma membrane, alveoli and a single partial layer of microtubules. Specialized cytoplasm lines the posterior end of this border. Or...

A cross section of cilium through the cilium-basal body complex extending from the cilium to the transition zone between the cilium and basal body and ending at the proximal tip of the basal body. Bar...

An electron micrograph of a thin frozen section treated with a clone of the mAb (D40-2) used to show the A4 antigen on decorated tubules. The immunogold lies along the outer margin of these tubules fo...

An image of the cytoplasm of Tetrahymena. Mitochondria have tubular cristae, infoldings of their inner membranes. Peroxisomes, with a few tubular inclusions, mucocysts, and a planar view of rough ER, ...

Phagoacidosomes are heavily labeled for L1 antigen in 5-8 to 15-18 minute-old DVs. However, only some DVs at 15-18 min still had L1 label. Only occasionally did we see tubules with label arising from ...

Dictyosomal elements of the Golgi complex consist of a layer of coated transition vesicles next to a specialized area of ER called the transition zone and two or three highly fenestrated layers of cis...
