Previous studies using the patch-clamp technique demonstrated the presence of a small conductance Cl(-) channel in the apical membrane of respiratory gill cells in primary culture originating from sea bass Dicentrarchus labrax. We used the same technique here to characterize potassium channels in this model. A K(+) channel of 123 +/- 3 pS was identified in the cell-attached configuration with 140 mM KCl in the bath and in the pipette. The activity of the channel declined rapidly with time and… CONTINUE READING
