Shown is a screenshot from a recording on a 4-channel Patchliner from HEK293 cells expressing TRPA1. Currents were activated by ca. 20 s application of 3 μM AITC followed by wash out. On the left raw whole cell currents as responses to 0.2 s voltage ramps (−100 mV to +100 mV) which were applied every 10 s are shown. On the right currents at +95 mV are plotted against time.
