xl-MCC are present in mitochondria from HeLa cells. a Representative tracings of single-channel events at a test potential of −100 mV showing activity of xl-MCC. b Corresponding amplitude histogram constructed from traces shown in (a). c Average of individual traces shown in (a). d An exemplary recording from HeLa mitoplast showing coexistence of channels with bursting activity, i-MCC and xl-MCC in the same patch
