Molecular Cytochemistry of Freeze-Fractured Cells: Freeze-Etching, Fracture-Label, Fracture-Permeation, and Label-Fracture [PDF]

Advances in Molecular and Cell Biology, 1987
Publisher Summary This chapter describes three alternative techniques for the cytochemical characterization of the components (membrane associated or not) that are exposed by freeze-fracture. The first, fracture-label permits the labeling of plasma and intracellular membranes (as well as cytoplasms and nucleoplasms) after freeze-fracture. The second,

Fusion of secretory vesicles isolated from rat liver [PDF]

, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.

Xylem surfactants introduce a new element to the cohesion-tension theory [PDF]

, 2016
Vascular plants transport water under negative pressure without constantly creating gas bubbles that would disable their hydraulic systems. Attempts to replicate this feat in artificial systems almost invariably result in bubble formation, except under ...
