TRP Channel Electrophysiology

Figure 1: Representative TRPA1 current traces before (grey line) and during the presence of increasing concentrations of the blocker A967079 (blue lines). A 300 ms ramp protocol from -60 mV to +60 mV, from a holding potential of +0 mV and repeated every 30 seconds is used to monitor the TRPA1 current.
