Voltage-clamp and single channel analysis of Pb(2+)-induced current in isolated snail neurons

Acta Biol Hung. 1993;44(1):3-7.

Abstract

Pb-activated outward current was investigated in intracellularly perfused, isolated snail neurons. Pb-ions induced non-inactivating but reversible current (IPb). The IPb showed concentration dependence. The I-V curve was linear with negative slope and the IPb proved to be Na-dependent.
