Fig. 8. High K+ regular Cl− diet has no effect on the basolateral ClC-K2/b channel in collecting duct intercalated cells.

Fig. 8

Representative macroscopic currents in response to voltage steps from − 90 to + 60 mV (shown in inset) from the holding potential of − 60 mV (a) and averaged current-voltage (I–V) relations (b) in intercalated cells from mice kept on regular diet (0.9% K+, 0.5% Cl−: RK+ RCl−, black) and high K+ regular Cl− diet (6% K+, 0.5% Cl−: HK+ RCl−, gray). c Representative continuous current traces from cell-attached patches monitoring basolateral 10 pS ClC-K2/b single channel activity in collecting duct intercalated cells for the regular (left) and high K+ (right) conditions. Patches were clamped to −Vp = − 60 mV. “C” denotes non-conducting closed state. Summary graph of changes in open probability (d), number of active channels within a patch (e), and unitary current amplitude (f) of ClC-K2/b in intercalated cells from mice on regular diet and high K+ regular Cl− diet
