Secondary lysosomes in quick-freeze deep-etch images lie against the smooth E-face of a phagoacidosome (DV-II) membrane. The P-fracture face of one fairly large lysosome lies close to the DV-II but no...

The infraciliary lattice in this quick-freeze deep-etched image consists of a meshwork of branching fibers composed of many subfibers. Basal bodies and trichocyst tips extend through the openings of t...

A cell with a flat alveolar sac system. It is not clear why some cells have expanded alveoli and others have flattened alveoli. Cacodylate buffered fixative. TEM taken on 2/3/69 by R. Allen with Phil...

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 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 surround...

A high resolution image of a clump of at least seven small clathrin cages that are probably connected to an early endosome (below the fracture plane). The morphology of these cages shows a tighter pac...

A 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 the smooth spo...

Higher resolution of the area that shows the clathrin-coated cage near the peniculus and clathrin coated preendosomal and partially coated preendosomal vesicles. Early endosomes like the preendosomal ...

Quick-freeze deep-etch of an ampulla. The P-fracture face has numerous IMPs. The microtubular ribbon now forms two bands next to this ampulla. The ribbons will split into additional bands as they pass...

Peroxisomes are sometimes associated with lipid bodies as they are in this example. This cell was pretreated with 4% DMSO which increases the permeability of its membranes. Thus the peroxisomes are st...
