Higher magnification of a QF-DE image of an acidosome with a large inward indentation of its membrane. The fractured P-face of the indentation shows many large IMPs. The acidosome lumen is honeycombed...

The cytopharynx/nascent digestive vacuole (phagosome) has an E-fracture face containing a high number of IMPs. Interestingly these IMPs are sometimes organized into plaques where there are several sho...

In addition to plates the plasma membrane contains IMPs on its P-fracture face in ring or parenthesis shape at sites of trichocyst secretion. A ring actually consists of two circles of IMPs and signif...

Quick-freeze deep-etch of granulo-fibrillar material at the crests of the ridges. This material is composed of thinner and shorter filaments that, like the striated bands, appear to bind to the membra...

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...

A high resolution image of portion of an isolated cilium exposing two rows of outer dynein arms arising from subfiber A of each doublet. The heavy chains of the dynein complex are linked to the microt...

High resolution image of an isolated and longitudinally fractured cilium exposing the middle of the cilium. The spokes extend from the doublets toward the two singlet microtubules. These spokes are sp...

High resolution view of the E-face of the fractured collecting canal of the contractile vacuole showing its association with microtubular ribbons and with the smooth spongiome. The E-fracture face of ...

High resolution view of quick-freeze deep-etch of the contractile vacuole E-fracture face. This face, like the collecting canal membrane, is porous indicating that many IMPs have been removed from thi...
