Fig 4. Effect of tolbutamide on channel gating behavior at +20, 0 and -10 mV.

Fig 4

Examples of single channel recordings in control conditions (200/50 mMKCl; cis/trans), and immediately after cis addition of tolbutamide 400 μM (n = 5). Tolbutamide caused a total voltage independent inhibition of channel activity. The—indicates the closed levels.
