Did you know that if ET capacity is lower than OXPHOS capacity (P>E) in living cells or mitochondrial preparations, then you have encountered an experimental artefact? The possible triggers of this experimental artefact are: - loss of oxidative capacity during the time course of the respirometric assay, - insufficient uncoupler concentrations, - over titration of an uncoupler, which inhibits ET capacity, - inhibition of ET capacity due to the use of high oligomycin (inhibitor of the ATP synthase) concentrations employed to measure LEAK respiration prior ET capacity.
