Description
Abbreviation: CCP-ce short
Reference: A: - SUIT-003
SUIT number: D009_ce1;ce2Omy;ce3U;ce4Rot;ce5Ama
O2k-Application: O2
- MitoPedia: SUIT - Coupling control protocol (CCP) in living cells (ce) with oligomycin (LEAK state)
- SUIT protocol pattern: ce1;ce2Omy;ce3U
The SUIT-003 O2 ce D009 (CCP-ce) is designed to study coupling control of living cells. Respiratory capacities are tested in a sequence of coupling states: ROUTINE, LEAK respiration and Electron transfer pathway. 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.

Strengths and limitations
- The CCP-ce (SUIT-003 O2 ce D009) is a coupling control protocol for living cells. In a living cell population, 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 module. See CCV SUIT-003 O2 ce-pce D020.
- CIV-activity can also be measured after application of the cell viability module.
- + Short duration of the experiment.
- - The concentration 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.

- In this ceCCP, ROX is measured after stepwise titration of rotenone (ce4Rot) and antimycin A (ce5Ama). In many living cells, Rox measured after titration of rotenone (ce4Rot) is not or only slightly further inhibited by subsequent addition of antimycin A (ce5Ama).
