Strengths and limitations
- Protocol focused on analysis of glutamate dehydrogenase anaplerotic pathway/glutaminolysis.
- + The use of glutamate alone allows to analyse the glutamate dehydrogenase anaplerotic pathway control state.
- + Short duration of the experiment.
- + Glutamate is easier to prepare compared to pyruvate.
- + CIV activity can be measured after this protocol.
- - Analysis of N-OXPHOS capacity (instead of NS-OXPHOS capacity) does not provide the best estimate of maximum mitochondrial respiratory capacity.
- - This protocol does not address questions regarding the convergence of pathways at the Q-junction.
- - Careful washing is required after the experiment to avoid carry-over of inhibitors and uncoupler.
