Freeze fracture image of the surface ridges at the anterior end of the cell where kineties to the right and left sides come together at an angle at the anterior suture tip. In this area are numerous p...

Conventional freeze-fractured images of DV-III membrane also suggests a transformation from a membrane with a smooth E-fracture face to one with characteristic large IMPs on its E-fracture face. The D...

Quick-freeze deep-etch image of a DV-III containing paracrystalline sheets in its lumen. The sheets have parallel rows of subunits spaced at 20nm center-to-center but the chemical nature of the sheets...

In this image a portion of the true surface of the plasma membrane is exposed where the culture medium has been etched away. The IMPs of the plates can also be viewed less distinctly on the true surfa...

Isolated mitochondria that have been quick-frozen, fractured and deep-etched show some space between the inner and outer membranes. Arcs of tubules, where they are tangentially fractured, show the hel...

The plasma membrane of Paramecium multimicronucleatum seen in a freeze fracture replica. The two rows of IMPs can be seen on the P-face of the plasma membrane that connects the plasma membrane to the ...

Cross fracture of cilia of the quadrulus. The basal body/cilium complexes are a little less tightly packed than in the peniculus. There are four or five rows of parasomal sacs interspersed with basal...

The plasma membrane of Paramecium multimicronucleatum seen in a freeze fracture replica. The two rows of IMPs can be seen on the P-face of the plasma membrane that connects the plasma membrane to the ...

Quick-freeze deep-etch images show a more three dimensional view of acidosomes surrounding a phagosome. Acidosomes are unique in that they contain indentations of their membrane. The lumen has a honey...

A high magnification view of the intimate docking of acidosomes with the phagosome is particularly apparent where the P-face of the acidosome lies against the E-face of the phagosome. Numerous large I...
