  • Title: [Evidence for existence of pores in intramembranous particles revealed by freeze fracturing].
    Author: Orci L, Perrelet A, Malaisse-Lagae F, Vassalli P.
    Journal: C R Acad Hebd Seances Acad Sci D; 1976 Nov 22; 283(13):1509-10. PubMed ID: 187354.
    Abstract:
    In freeze-fracture replicas of membranes (plasma and intracellular) in a variety of animal cells, it is possible to detect the presence of intramembrane particles containing an electron-dense spot. The spot is interpreted as an accumulation of platinum into a cavity; the cavity could in turn correspond to a hydrophilic pore in the particle.
