SUIT-003 O2 ce-pce D018 is designed to study coupling control and plasma membrane permeability of living cells. Respiratory capacities are tested in a sequence of coupling states: ROUTINE, LEAK respiration and Electron transfer pathway in the presence of glucose. To study LEAK respiration, the phosphorylation system is inhibited by oligomycin. The final concentration of oligomycin has to be carefully optimized for various cell types, to minimize the inhibitory effect on the electron transfer system which would lead to an underestimation of ET capacity. At Electron transfer pathway state, glucose is added to test the Crabtree effect on living cells. The viability index, VI, in the simple CCVP-Glc (SUIT-003 O2 ce-pce D018) may be underestimated if succinate uptake in the living cells proceeds through the dicarboxylate carrier of the plasma membrane. CCVP-Glc can be extended by the Complex IV module.

Strengths and limitations
- The SUIT-003 O2 ce-pce D018 is a cell coupling-control protocol. The total cell count (Nce) is the sum of viable cells (Nvce) and dead cells (Ndce).
- When MiR05 is used, the addition of pyruvate is recommended to provide an external fuel substrate.
- CIV activity can also be measured after the cell viability test module.
- + With the extended module, S-ET capacity can be assessed after the performance of the coupling-control protocol, as well as outer mt-membrane integrity with the addition of cytochrome c.
- - The addition of oligomycin has to be carefully tested to avoid inhibitory effects in the evaluation of the ET-capacity.
- - Careful washing is required after the experiment to avoid carry-over of inhibitors and uncoupler.
