Correlation between the activation properties of ASIC1a and ASIC1b and their inhibition by 9AA. A, pH-dependencies of the response amplitude for ASIC1a (black dots) and ASIC1b (red dots) activation. B, representative examples of ASIC1b channel currents evoked by different pHs. The interval between applications is 60 s. C, concentration dependencies of ASIC1a (black dots) and ASIC1b (red dots) inhibition by 9AA. D, representative examples of ASIC1b currents at pH=6.2 in the presence of different 9AA concentrations
