Pilot experiments of Hcn2 and SkM1 currents measured at 36°C and room temperature, respectively, in single nucleofected CPCs. (A) Top panel, protocol used. Middle panel, recording of an empty CPC. Bottom panel, Hcn2-encoded “funny current” (at test potentials ranging from –30 to –120 mV) in an Hcn2 nucleofected CPC. (B) Top panel, protocol used. Middle panel, recording of an empty CPC. Bottom panel, skeletal fast sodium current (at test potentials ranging from –50 to +20 mV) in a SkM1 nucleofected CPC. SkM1 was measured from a holding potential of –140 mV.
