Details of the binding of the carrier vesicle to a microtubule. Four bridges, thought to be cytoplasmic dynein arms, span the 40nm space between these two structures. The membrane of the vesicle has b...

The carrier vesicles dock with the acidosomes and then fuse with these larger vesicles before or as the vesicles dock at the nascent Digestive Vacuole. Thus the contents of the carrier vesicles are fi...

Rabbit skeletal muscle fibers were minced in an ATP-containing relaxing buffer and dissociated into thick and thin filaments by mild blending. The isolated filaments were then deposited onto mica fla...

Higher resolution image of the area that shows the clathrin-coated cage near the peniculus and clathrin coated preendosomal and partially coated preendosomal vesicles. Early endosomes like the preendo...

High resolution image of quick-freeze deep-etch rotary-shadowed replica of an early endosome with two clathrin-coated evaginations. Presumably these coated pits contain receptors for cargo that will b...

High resolution view of an early endosome with at least two coated evaginations showing, lies next to the proximal end of a fractured basal body. Other clathrin cages may indicate other evaginations f...

An isolated and longitudinally fractured cilium exposing the middle of the cilium. The spokes extend from the doublets toward the two singlet microtubules. These spokes are spaced unevenly so they app...

Quick-freeze deep-etch image of a fracture through the radial canal of the contractile vacuole. This technique presents a picture of a confusing array of non-etchable material surrounding a collecting...

In quick-freeze deep-etch preparations in which cells are slam frozen the pellicle and the plasma membrane tends to be flattened. The double rings are present but only the outer ring of IMPs stand out...

In a conventional freeze fracture view the membrane around the trichocyst tip is decorated with striations and IMPs. These decorations are found at the site where the trichocyst tip is associated with...
