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...

High magnification of early endosomes in which the membranes are easily seen as a tripartite track. Gold, labeling antigen C6 is observed only in the body of the early endosome and not in the coated e...

This micrograph shows the pegs on the surface of the decorated tubules associated with the contractile vacuole that are negatively stained by the uranyl acetate dissolved in the methylcellulose soluti...

An image of the nucleoli of the macronucleus. Nucleoli have a core of DNA that contains the genes that are transcribed into ribosomal RNA. Assembly of the ribosomal subunits from this processed RNA an...

Most wild type Tetrahymena have a macronucleus and a micronucleus. The micronucleus, seen here, is essentially nonfunctional during interphase. Its function is to replicate and pass a complete copy of...

An image of the cortex of Tetrahymena showing a longitudinal microtubular ribbon sandwiched between the alveoli and the epiplasm in the crest of the pellicular ridge. A parasomal sac, the distal end o...

A mAb, B25-1-3, was raised to antigen Q2 (arbitrary code) to the same set of membranes as mAb 132-F4-G6 labels. This mAb was more reactive on frozen sections. To tell the age of vacuoles, cells were e...

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...

Following discharge, remnant trichocyst membrane does not appear to directly enter the trans Golgi network for reuse in new trichocyst formation. Rather the HRP will be transferred to lysosomes (not s...
