The Effect of Changing External Na+ on the Steady State Charge Distribution
| Na+ (mM) | 96 | 50 | 25 | |||
|---|---|---|---|---|---|---|
| z | 0.48 ± 0.03 | 0.51 ± 0.03 | 0.46 ± 0.02 | |||
| ΔV0.5 (mV) | 0 | −16.4 ± 2.6 | −24.7 ± 2.5 | |||
| Qmax/Qmax (96) | 1.0 | 0.88 ± 0.02 | 0.78 ± 0.03 |
Fit parameters obtained from fitting the Boltzmann function (Eq. 2) to the Q-V data (mean ± SEM, N = 4). ΔV0.5 is the shift in V0.5 relative to the value at 96 mM Na+.
