The window opened 20 … WebJan 1, 1981 · In a Woods Hole squid, total gating charge movement is typically about 1200 electronic charges/μm 2, and if there are 6 electronic charges/channel, then there are approximately 200 channels/μm 2. This is quite consistent with current estimates of the conductance of a single sodium channel. No one, however, should be surprised if there …
