A DV-III contains a thick continuous glycocalyx (polysaccharide coat) on the luminal side of its membrane as well as paracrystalline material, both provided by the fused lysosomes. The latex beads ind...

This image of Halteria was fixed in cacodylate-buffered fixative and stained. The round, dark bodies, possibly pigment granules, were transparent in other preparations are electron-opaque following th...

A high resolution image of a cell actively undergoing endocytosis that develops an extensive layer of vesicles and cisternae composed for the most part of smooth undecorated membrane. The uncoated cis...

COP-I beta1 (green) staining at the Golgi (GM130, a cis-Golgi marker) (red) in unstimulated HeLa cells. Helix Pomatia Lectin (HPL) (gray) staining is also shown. HPL binds various glycans but the Tn a...

Quick-freeze deep-etch image of a fracture through the radial canal of the contractile vacuole. This technique presents a picture of a confusing array of non-etchable material surrounding a collecting...

The two CV pores of a cell. An impression of the helically wound microtubules are detectable in the right pore. TEM taken on 4/21/78 by R. Allen with Hitachi HU11A operating at 60kV. Neg. 21,750X. Bar...

An electron micrograph of a thin frozen section treated with a clone of the mAb (D40-2) used to show the A4 antigen on decorated tubules. The immunogold lies along the outer margin of these tubules fo...

Some tubules near a contractile vacuole which appear to be decorated with pegs similar to the spongiome of the CV of Paramecium. In Paramecium these pegs are known to be V-type proton pumps (V-ATPases...

The nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...
