Recordings of KATP current in Xenopus oocytes injected with Kir6.1/SUR2B, Kir6.2/SUR2B, Kir 6.1/SUR1 and Kir6.2/SUR1 mRNAs, as indicated. 98 K and 2 K solutions were perfused, as indicated by the arrows. For Kir6.1/SUR2B and Kir6.2/SUR2B, 100 μM pinacidil was added to the extracellular solution to activate currents. For Kir 6.1/SUR1 and Kir6.2/SUR1, 100 μM diazoxide and 10 μM CCCP were added to activate currents. PNU-37883A and glibenclamide were added in the presence of pinacidil or diazoxide/CCCP. Membrane current was measured at a potential of −60 mV, and the dashed line indicates the zero current level.
