Inhibition of I_K (% of reduction) induced by different potassium channel inhibitors in A7r5 cells. The bars represent the effect on I_K of the following potassium channel blockers: the K_V channel blocker 4-aminopyridine (4-AP; 2 mmol/L); the BK_Ca channel blocker tetraethylammonium (TEA; 1 mmol/L); the low conductance K_Ca channels blocker apamin (APM, 10 μmol/L); and the K_ATP channel blocker glibenclamide (GLI; 10 μmol/L). Each column represents the mean value±SEM (indicated in vertical bars), in percence of the inhibition of I_K from the number of experiments shown in brackets.
