Description
Abbreviation: RLE
Reference: A Huetter 2004 Biochem J
MitoPedia concepts:
SUIT protocol,
SUIT A
- SUIT-category: RLE
- SUIT protocol pattern: linear coupling control protocol (CCP)
References
- The CCP diagram may show the respiratory states directly (left) as an alternative to presenting the titration steps.
- Rot and Ama
- In this CCP, ROX is measured after titration of rotenone, antimycin A, or both in a single step. Validity of using rotenone only for inducing ROX in intact cells is evaluated by stepwise measurement of ROX after titration of rotenone (3Rot) followed by titration of animycin A (4Ama).

- 1R;1Omy;2U;3Rot;4Ama
- Rot and Ama
- In this CCP, ROX is measured after stepwise titration of rotenone (3Rot) and antimycin A (4Ama). In many intact cells ROX measured after titration of rotenone (3Rot) is not or only slightly further inhibited by subsequent titration of animycin A (4Ama).
- Respiration in senescent human primary fibroblasts (0.2Γ106 cells/ml). Arrows show steps in the titration regime of the coupling control protocol, inducing the following respiratory states: ROUTINE (R; routine state in cell-culture medium); LEAK (L; inhibition of ATPsynthase by 1 ΞΌg/ml oligomycin); ETS (E; maximal stimulation by uncoupling of oxidative phosphorylation in four subsequent titrations of the uncoupler, U, FCCP (2.5β4 ΞΌM final concentration); ROX (rotenone, Rot, and antimycin A; residual oxygen consumption). Modified after Huetter_2004_Biochem J.
