Reference: B Carrier control for the coupling control protocol for living cells with cell permeable compounds MitoKit-CII/Succinate-nv and MitoKit-CII/Malonate-nv - SUIT-003 O2 ce D060

O2k-Application: O2
- MitoPedia: SUIT - Coupling control protocol (CCP) with the carrier of the plasma membrane-permeable succinate (MitoKit-CII/Succinate-nv) and plasma membrane-permeable malonate (MitoKit-CII/Malonate-nv) in living cells (ce): DMSO.
- SUIT protocol pattern: ce1;(ce2Omy);ce3U;ce4DMSO;ce5DMSO;ce6Rot;ce7Ama
SUIT-003 O2 ce D061 protocol is a control for the SUIT-003 O2 ce D060, with the addition of the carrier DMSO instead of the plasma membrane-permeable succinate ([[[MitoKit-CII/Succinate-nv]]) and plasma membrane-permeable malonate (MitoKit-CII/Malonate-nv). Moreover, the SUIT-003 O2 ce D061 protocol allows evaluating the coupling control of living cells. Respiratory capacities are tested in a sequence of coupling states: ROUTINE and ET. Optionally, to study LEAK-respiration, the phosphorylation system might be 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
- + This protocol is a control for SUIT-003 O2 ce D060, with titrations of the carrier DMSO.
- + Reasonable duration of the experiment.
- - To obtain LEAK respiration, 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.
