Ruthenium red suppresses the activities of mitochondrial Ca²⁺ channels. a, b Representative traces showing the activities of b-MCC at test potential of −150 mV (a) and xl-MCC at test potential of −100 mV (b) before (control) and after addition of 1 and 10 μM RuR into the bath solution. Recordings were performed in the bath solution containing 40 mM Cl⁻ in the absence (a) and presence (b) of 100 μM DIDS in the pipette solution
