Guanidinium analogues as probes of the squid axon sodium pore. Evidence for internal surface charges
We have investigated the reduction of steady state sodium channel currents by a monovalent and a divalent guanidinium analogue. The amount of block by the divalent compound at a constant membrane potential was dramatically reduced by an increase in the internal salt concentration. Channel block by t...
