Fig. 48: freeze fracture of DV-III membrane

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 DV-III membrane resembles the lysosomal membrane which also has a moderate number of large IMPs on its E-fracture face (Fig. 36). (For freeze-fracture study of DVs see Allen and Staehelin, J. Cell Biol. 89:9-20, 1981). EM taken on 2/16/76 by R. Allen with JEM-100B TEM. Neg. 31,193X. Bar = 0.2µm.
