Single K+ channel properties in cultured mouse Schwann cells: conductance and kinetics.

Cultured Schwann cells are characterized by a strong outward rectification of the membrane; the threshold of the outward currents is close to the resting membrane potential of about -50 mV (Gray et al.: In Ritchie, Keynes (eds): Ion Channels in Neural Membranes. New York: Alan R. Liss, Inc., pp 145-157, 1986). These outward currents show up a heterogeneity… (More)
