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

Quick-freeze deep-etch image of rows of carrier vesicles lined up along the cytopharyngeal microtubular ribbons. These vesicles arise from early endosomes as clathrin coated vesicles and are about 100...

High resolution image of vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch pre...

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 be pinched off from the ea...

In some cells exposed to horseradish peroxidase (HRP) for 30 sec and then immediately fixed some HRP has already entered the cell by endocytosis and has been removed from the early endosomes in carrie...

Two parasomal sacs that are oriented perpendicular to the basal bodies. The top parasomal sac has a clathrin cage around it's coated pit area. The P-face of the plasma membrane has some IMPs, particul...

An early endosome in planar view that contains HRP-reaction product. This cell was exposed to HRP for 6 min. and then fixed. This early endosome had two small coated evaginations arising from its rim ...

Vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch preparation. Preendosomal ve...

Receptor mediated endocytosis is a process in which extracellular molecules are taken into the cell via coated vesicles that pinch from the plasma membrane. In Paramecium the resulting vesicles fuse w...
