Table 1 Acid dependent effects on the activation rate of capsaicin-activated responses. Increasing the acidity of the external solution during a 1 second pre-pulse resulted in an increase in the activation rate of capsaicin-evoked currents in rat TRPV1 expressing HEK-293 cells. Values are the mean ± SEM of the calculated activation rate (τ) using a single exponential fit.
