Description
Abbreviation: RP2 ce-pce
Reference: A - SUIT-002
SUIT number: D007_ce1;1Dig;1D;2M;3Oct;3c;4M;5P;6G;7S;8Gp;9U;10Rot;11Ama;12AsTm;13Azd
O2k-Application: O2
- MitoPedia: SUIT - SUIT reference protocol Reference protocol RP2 for living cells (ce, ROUTINE respiration) and cells that are permeabilized in the chamber (pce)
- SUIT protocol pattern: 1D;2M.1;3Oct;3c;4M2;5P;6G;7S;8Gp;9U;10Rot-
The SUIT-001 O2 pfi D002 protocol in combination with SUIT-002_O2_pfi_D006 is specially designed to provide a common reference for comparison of respiratory control of permeabilized fibers in a wide variety of species and tissues. SUIT-001 O2 pfi D002 gives information of the linear coupling control (L- P- E) with NADH linked-substrates (PM). Moreover, the pathway control in ET state (N, NS, FNS, S and SGp pathways) can be evaluated by using this SUIT protocol. SUIT-001 O2 pfi D002 can be extended with the CIV assay module.

Strengths and limitations
- SUIT-002 in combination with SUIT-001 provides a common reference for comparison of respiratory control in a large variety of species, tissues and cell types. Both SUIT protocols provide a mitochondrial mapping which allows:
- 1. to obtain reference values.
- 2. to evaluate mitochondrial physiological diversity, generating a mt-database on comparative mitochondrial physiology.
- 3. to screen specific defects.
- SUIT-001 and SUIT-002 are used in the MitoFit Proficiency test for inter-individual and inter-laboratory reproducibility quality control.
- A succinate concentration of >10 mM may be required for saturating SE capacity.
- + SUIT-002 allows the depletion of endogenous substrates with ADP (1D).
- + The protocol provides information on F-pathway in OXPHOS state. The low concentration of malate used in this protocol, typically 0.1 mM, does not saturate the N-pathway; but saturates the F-pathway.
- + F-pathway (3Oct-2M.1) can be compared to FN-pathway (5P) in OXPHOS state.
- + Pathway control in OXPHOS (F, F(N), FN, FNS, FNSGp pathways) and in ET state (FNSGp and SGp) can be observed.
- + Harmonization with SUIT-001 allows to perform both SUIT protocols in parallel. The cross-linked respiratory states can be statistically used as repeated measurements.
- + Harmonization with many SUIT protocols (up to step 7S).
- + In SUIT-002, the full set of pathways converging into Q (FNSGp) is obtained in OXPHOS and ET states. Therefore, P/E (8Gp/9U) at high ET capacity can be calculated.
- + This protocol can be extended with the Complex IV module.
- + The addition of non-permeabilized cells to the chambers provides additional information (ROUTINE respiration) which can not be obtained in SUIT-002 O2 mt D005 where the cells added to the chambers are already permeabilized.
- - S-pathway in ET state is not obtained (it is obtained in SUIT-001).
- - Lengthy duration of the experiment.
Compare SUIT protocols
- SUIT-002 O2 ce-pce D007 (general SUIT-002 for permeabilized cells) differs from SUIT-002 O2 ce-pce D007a (SUIT-002 for permeabilized PBMCs and PLTs) in the concentration and volume of the titrations.
- SUIT-001 O2 ce-pce D003 (RP1): Harmonized SUIT protocol for permeabilized cells (non-permeabilized cells must be added to the chambers and then permeabilized as a part of the protocol).
- SUIT-002 O2 mt D005: SUIT-002 for permeabilized cells (cells added to the chamber have been permeabilized before their addition). This SUIT protocol provides no information on ROUTINE respiration of non-permeabilized cells (ce).
