Figure 7. CyPPA and SKA-31 had no effect on smooth muscle cells (SMCs) at physiological potentials.

A, CyPPA had no resolvable effect on membrane potentials (I= 0, blue dotted line) and currents (voltage-clamp at −40 mV, red dotted line). B, SKA-31 did not cause hyperpolarization (I= 0, blue dotted line) or activate outward currents at a holding potential of −40 mV (voltage-clamp, red dotted line).
