Title: Rotary-shadowed freeze-fracture replicas: a simple method for the analysis of fracture faces. Author: Smith CA, Carson JL, Collier AM. Journal: Stain Technol; 1985 Jan; 60(1):51-3. PubMed ID: 2579480. Abstract: In rotary-shadowed freeze-fracture replicas, intramembrane particles on the periphery of a membrane fracture face are not uniformly shadowed from all sides. Those eccentrically positioned intramembrane particles with a net centripetally directed shadowing are on a convex fracture face. In contrast, those eccentrically positioned intramembrane particles with a net centrifugally directed shadowing are on a concave fracture face. Centrally positioned intramembrane particles on convex faces are uniformly shadowed from all sides; however, central depressions of concave faces are often unshadowed.[Abstract] [Full Text] [Related] [New Search]
