Figure 6. High concentration of PCCP⁻ induce a current in non-injected Xenopus oocytes.

A, Voltage jump of 25 ms duration from −80 mV to −30 mV. A µA sized transient current flows with each voltage step. B, A small transient outward current is induced after applications of 10, 30 and 100 µM PCCP⁻ of 30 s duration to an oocyte held at a membrane potential of −80 mV.
