Single-channel currents of an intercellular junction

Nature. 1985 Sep 26-Oct 2;317(6035):331-5. doi: 10.1038/317331a0.


We have used a double whole-cell patch-clamp system to make the first quantitative recordings of the single-channel current from an intercellular junction, presumably a gap junction. The junctional channel has various conductance states and discriminates poorly between cations and anions. It seems to change slowly from one conductance state to another.
