  • Title: [Discrete parameters of current oscillation in single ion channels].
    Author: Geletiuk VI, Kazachenko VN.
    Journal: Biofizika; 1987; 32(2):269-72. PubMed ID: 2437961.
    Abstract:
    Using the patch-voltage-clamp method it was shown that oscillations of an open channel are fast current transitions between 64 multiple sublevels. Average values of elementary conductance step (gamma) and substate lifetime (tau el) were determined for different kinds of ionic channels. The values of gamma lie in the range from 1.5 to 6 pS, and tau el--in the range from 0.15 to 0.5 ms. The channel transitions between the substates are highly cooperative processes. The data are regarded in terms of the hypothesis about clustery organization of ionic channels.
