The protocols recommended in the SUIT-003 have been designed to study the coupling control state of living cells. In order to study the LEAK respiration, the phosphorylation system needs to be inhibited, which is achieved in this protocol using oligomycin. However, the oligomycin concentration has to be carefully adjusted for different samples and the inhibitory effect on the electron transfer system has to be studied to avoid an underestimation of the ET capacity. SUIT-003 follows a modular approach and can be easily used in combination with the permeability test and/or the assessment of the complex IV capacity.

Strengths and limitations
- The SUIT-003 is a cell coupling-control protocol. The total cell count (Nce) is the sum of viable cells (Nvce) and dead cells (Ndce).
- This protocol can be extended with the cell viability test module.
- For determination of respirometric viability index, it is assumed that both viable and dead cells contain functional mitochondria.
- When the cell viability test module is not incorporated to the experiment, complex III inhibitors should be used to reach Rox instead of rotenone.
- When MiR05 is used, the addition of pyruvate is recommended to provide an external fuel substrate.
- + Respirometric cell viability test correlates with other cell viability quantification methods.
- + With the extended module (SUIT-003 O2 ce-pce D020), S-ET capacity can be assessed after the performance of the coupling-control protocol, as well as outer mt-membrane integrity with addition of cytochrome c.
- + CIV activity can also be measured after the cell viability test module.
- + Flexibility of experiment duration: from 1 hour (cell coupling-control protocol) to 2 and a half hours (cell coupling control, cell viability test module and CIV module).
- + Reasonable duration of the experiment.
- - Cells with a cell membrane succinate transporter are not suitable for the viability test.
- - Pathological profiles could hinder the cell viability test.
- - Careful washing is required after the experiment to avoid carry-over of inhibitors and uncoupler.
