Tissue section of human prostate containing adenocarcinoma that has been immunostained for the cell-surface antigen CD49d. Nuclei are stained in blue. This image is part of a large collection of image...

Freeze-fracture preparation of the plasma membrane from an unspecialized area composed of Sertoli cells of the guinea pig testis. With the freeze-fracture technique, tissue is rapidly frozen and crac...

To study the cellular consequences of misfolding of plasma membrane proteins, a transmembrane model protein that was constitutively targeted to the plasma membrane was developed for use as a reporter ...

The F1F0 ATP synthase is a large protein complex that catalyzes the formation of ATP from ADP and inorganic phosphate using a proton gradient as a source of energy. In eukaryotes, the F1F0 ATP syntha...

The sequences in this videotape illustrate the unusual crawling motility of the amoeboid sperm of the nematode parasite, Ascaris suum, an intestinal parasite of pigs. Ascaris sperm contain no myosins ...

This simulation shows a dynamic molecular model of the bacterial cytoplasm, giving us a spectacular glimpse of the crowded conditions of the interior of a cell over a brief 15-microsecond time span. ...

Lily mitosis. A light microscope image of a cell from the endosperm of an African globe lily Haemanthus (Scadoxus) katherinae. This is one frame of a sequence that shows all phases of mitosis. The lil...
