Figure 9. Cell-attached patch recordings of a nonconnexin channel endogenous to Xenopus oocytes. (A) A record of a single channel at a holding potential of +30 and â50 mV. The channel has a unitary conductance of 20â25 pS at +30 mV and 30 pS at â50 mV. (B) Currents elicited by alternating ±90-mV voltage steps. The channels are slowly activated by depolarization (+90 mV). At hyperpolarizing membrane potentials (â90 mV), the activated channels close and appear to run down. (C) The currentâvoltage relation of the endogenous Xenopus oocyte channel resulting from a 3-s voltage ramp from +100 to â100 mV. Baseline currents were not adjusted. Image published in: Oh S et al.
