Model results compared to the experiments of Frank et al. (1999) (low-frequency conditions)
| Shift in the membrane potential (mV) | Slope (nm/mV) |
 (N/Vm) |
Computed force (pN/mV) | Measured force (pN/mV) |
|---|---|---|---|---|
| 0 | 4.5 | 0.0029/0.0018 | 57.2 | 13.0 |
| −50 | 2.2 | 0.0014/0.00088 | 28.0 | |
| −100 | 1.0 | 0.00064/0.0004 | 12.7 |
The slope is estimated according to Figure 6 of Dallos et al. (1993). It is assumed that 
at two different points changes with corresponding slopes in the same proportion. The measured force is from Frank et al. (1999). Stiffness of the mechanical constraint against the cell end is 0.17 N/m. All forces were determined under low-frequency conditions.
