Description
Abbreviation: RP1 ce-pce
Reference: A - SUIT-001 - SUIT reference protocol Reference protocol RP1 for living cells (ce, ROUTINE respiration) and cells permeabilized in the respirometric chamber (pce)
SUIT number: D003_ce1;1Dig;1PM;2D;2c;3U;4G;5S;6Oct;7Rot;8Gp;9Ama;10AsTm;11Azd
O2k-Application: O2
The SUIT-001 O2 ce-pce D003 protocol in combination with SUIT-002 O2 ce-pce D007 is specially designed to provide a common reference for comparison of respiratory control of permeabilized cells (non-permeabilized cells must be added to the chambers and then permeabilized as a part of the protocol) in a wide variety of cell types. SUIT-001 O2 ce-pce D003 gives information on ROUTINE respiration (ce: non-permeabilized cells) and after the plasma membrane permeabilization (pce: permeabilized cells) on 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 ce-pce D003 can be extended with the CIV assay module.

Strengths and limitations
- SUIT-001 in combination with SUIT-002 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 to:
- 1. obtain reference values;
- 2. evaluate mitochondrial physiological diversity, generating a mt-database on comparative mitochondrial physiology;
- 3. screen specific defects.
- SUIT-001 and SUIT-002 are used in the MitoFit Proficiency test for inter-individual and inter-laboratory reproducibility as quality control.
- A succinate concentration of >10 mM may be required for saturating SE capacity.
- + Linear coupling control (L-P-E) with N substrates (PM).
- + Pathway control in ET state (N, NS, FNS, S and SGp pathways).
- + Harmonization with SUIT-002 allows to perform both SUIT protocols in parallel. The cross-linked respiratory states can be statistically used as repeated measurements.
- + In cells, SUIT-001 and SUIT-002 harmonize in: ROUTINE (ce1), SGpE (8Gp in SUIT-001 and 10Rot in SUIT-002) and Complex IV.
- + Harmonization with many SUIT protocols (up to step 5S).
- + Oct is added in ET state to avoid uncoupler effect with fatty acids.
- + The additivity index of N- and S-pathways in ET state can be evaluated.
- + 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 is not obtained in SUIT-001 O2 mt D001 where the cells added to the chambers are already permeabilized.
- - The substrate combination for maximum ET capacity (FNSGp) is not obtained in SUIT-001 in favor of measuring SE.
- - Long duration of the experiment.
Compare SUIT protocols
- SUIT-001 O2 ce-pce D004: SUIT-001 O2 ce-pce D003 (general SUIT-001 for permeabilized cells) differs from SUIT-001 O2 ce-pce D004 (SUIT-001 for permeabilized PBMC and PLT) in the presence and absence of octanoylcarnitine, respectively.
- SUIT-002 O2 ce-pce D007 (RP2): 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-001 O2 mt D001: SUIT-001 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).
