Figure 1.
Mitoplast patch-clamp measurement and single-channel recordings of channels observed after transient transfection with the BKCa VEDEC-encoding plasmid. (A) Schematic depiction of the patch-clamp channel measurement of the inner mitochondrial membrane: mitoplast preparation and single-channel patches in the inside-out configuration. (B) Representative recording of single- and (C) multiple-channel activity in the patch of the inner mitochondrial membranes after transient transfection of HEK293T cells with the BKCa VEDEC-encoding plasmid. Single- and six-mitoBKCa channel activities are presented. Recordings were performed at holding potential + 40 mV.
