Figure 5. Voltage dependence of inactivation of Na_V1.7 and Na_V1.3 currents in αTC1‐6 and CHO cells.

A, voltage dependence of inactivation of Na_V1.7 currents when the α‐subunit is co­expressed with β₁‐ and β₂‐subunits in αTC1‐6 (red; n = 10) and CHO (black; n = 10) cells. The curve represents a single Boltzmann fit to the data and the grey dashed line represents the inactivation of Na_V1.7 expressed in Ins1 cells (shown in Fig. 3). B, same as in A, but experiments were conducted with Na_V1.3 in αTC1­6 (red; n = 9) and CHO cells (black; n = 13). See also Table 1. [Color figure can be viewed at http://wileyonlinelibrary.com]
