Effect of okadaic acid on channel activity in cell-attached patches. Channel activity was first reduced by addition of 200 μM ATP in bath solution, which could be prevented by pretreatment of the tubule with 2 μM okadaic acid. Three parts on the trace indicated by arrows were extended at fast time resolution. Channel closed states are indicated by dotted lines and C (n = 12).
