Figure 5. Effect of internal NFA on I-V relationship for ICl(Ca) activated by 500 nm[Ca2+]i.
I-V curves for ICl(Ca) before (Control, ○), during (+external 100 μm NFA, □) and after (Wash, ▵) application of external 100 μm NFA when the pipette solution contained 100 μm NFA as determined by depolarising voltage ramps from −100 to +100 mV. Currents have been normalised to the control current at −100 mV (-1). Points are means ± s.e.m. (n = 5). Overlapping standard error bars have been omitted for clarity.
