  • Title: Voltage-clamp analysis of the sodium and potassium currents in skeletal muscle fibres treated with 4-aminopyridine.
    Author: Molgó J.
    Journal: Experientia; 1978 Oct 15; 34(10):1275-9. PubMed ID: 738393.
    Abstract:
    External application of low concentrations of 4-aminopyridine blocks potassium currents without affecting sodium currents in pieces of single frog skeletal muscle fibres. The blockade of potassium currents was voltage-dependent, being partially relieved on depolarization.
