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...

Acidosomes originate from the biosynthetic pathway that includes the ER, the Golgi stack and the trans-Golgi network (TGN). Flattened vesicles from the TGN round up into spherical vesicles and bind to...

The image shows a portion of a slice through a 3D tomographic reconstruction of a mouse adenocarcinoma cell based on x-ray microscopy. Live cells were cryofixed by plunge freezing in liquid ethane an...

Didinium intiates capture of Paramecium. Believe-it-or-not, this Didinium may accomplish the ingestion of the Paramecium in less than one minute. See other images in the link below. Also showing metac...

Didinium ingests Paramecium. Note that Paramecium is nearly the waiting food vacuole and the proboscis of Didinium is beginning to reform. This micrograph also shows the metachronous waves of cilia in...

Didinium ingests Paramecium. Note that Paramecium is folded in half as it is compressed and enters the waiting food vacuole. This micrograph also shows a few discharged Paramecium trichocysts as well ...

Didinium ingests Paramecium. At the midpoint of engulfment, some 30 seconds after contact. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnif...

A high resolution image of a clump of at least seven small clathrin cages that are probably connected to an early endosome (below the fracture plane). The morphology of these cages shows a tighter pac...

Quick-freeze deep-etch rotary shadowed replica of a parasomal sac from which a clathrin-coated preendosomal vesicle has pinched off. The typical clathrin cage structure is preserved. Fractured trichoc...

A clump of at least seven small clathrin cages that are probably connected to an early endosome (below the fracture plane). The morphology of these cages shows a tighter packing than the larger clathr...
