Strengths and limitations

+ The protocol provides information on FAO capacity in the absence of other, potentially interfering pathways, both in the LEAK state and in OXPHOS.

+ FNS OXPHOS capacity comprises the most important pathways in many cell types and thus provides a physiologically relevant estimate of maximum mitochondrial respiratory capacity.

+ FNS ET capacity is a good estimate of overall ET capacity in many cell types.

+ The presence of PMG and S establishes a fully operative TCA cycle activity.

+ Reasonable duration of the experiment.

- F OXPHOS capacity may be underestimated. In human heart muscle addition of Oct to palmitoylcarnitine (Pal) + malate increased OXPHOS by 26% (Lemuieux et al 2011).

- SRot(E) may be underestimated if S is not saturating.

- CIV activity is not measured, to save experimental time.
