Transmission electron micrographs showing details of nuclear pores in thin sections of an erythroblast (above) and endothelial cell (below). Pores appear to be filled with dark staining material in th...

Transmission electron micrograph of surface of nuclear envelope of guinea pig spermatocyte prepared by the Freeze-fracture technique shows the unusual clustering of nuclear pores in these cells. From...

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 ...

Time-lapse experiments showing deltorphin II (100 nM; a selective agonist)-induced internalization of delta-opioid receptor–enhanced GFP (DOR-EGFP; green) receptors expressed in HEK 293 cells. The C...

The transmission electron micrograph shows stacked annulate lamellae from a human Sertoli cell. Annulate lamellae consist of sheets of membrane containing closely packed structures resembling nuclear...

Transmission electron micrograph of rat liver cell showing a grazing section through the nuclear envelope and illustrating the high density of nuclear pores in cells from a 1 day old animal. The cytop...

Freeze fracture images of synaptic junctions in the retina of Macaca mulatta. The electron micrograph in the top panel shows two invaginating synapses between cone and horizontal cells in the outer p...

High resolution image of the contractile vacuole and the spongiome decorated tubules showing V-type proton pumps extending from the cytosolic side of the tubules; also detail of the micronucleus. TEM ...

An image of the contractile vacuole and the spongiome decorated tubules showing V-type proton pumps extending from the cytosolic side of the tubules; also detail of the micronucleus. TEM taken on 6/10...

Immuno-gold labeling of corn stunt spiroplasma (CSS, Spiroplasma kunkelii, Class Mollicutes) in sieve elements and other phloem cells of infected maize root tissue. In this image, CSS appears to be cr...
