Description
Abbreviation: NS(P)
Reference: B: SUIT-009 short protocol for mt-respiration in pce.
SUIT number: D016_ce1;1Dig;1S;2D;3P;4Rot;5Ama
- SUIT-category: NS(P)
- SUIT protocol pattern: orthogonal 1S;2D;3P;4Rot;5Ama
Originially this is a short protocol for simultaneous determination of O2 flux and the rate of H2O2 production (H2O2 flux) on permeabilized cells. It is used as a control experiment forSUIT-009 AmR pce D019 without using the Amplex UltraRed assay in order to detect the effect of the fluorescence dye on the O2 flux. We do not recommend this protocol for determination of the O2 flux in the absence of Rotenone. For O2-Application with isolated mitochondria and tissue homogenate, choose SUIT-009 O2 mt D015; for O2 and H2O2 measurements (AmR) with permeabilized cells, choose: SUIT-009 AmR pce D019.

Strengths and limitations
- It is a protocol to investigate the S- and NS-pathway linked respiration.
- For H2O2-Application, choose SUIT-009 AmR pce D019.
- Cytochrome c test can be performed in the S-OXPHOS state.
- Reasonable duration of the experiment.
- + This protocol can be extended with the Complex IV module.
- - A succinate concentration > 10 mM might be required to reach saturating S-OXPHOS capacity.
- - In some cell lines e.g. HEK293T, P does not have any effect because of the downregulation of the N-linked pathway.
