The SUIT-001 protocol in combination with [[SUIT-002]] is specially designed to provide a common reference for comparison of respiratory control of [[Mitochondrial preparations| mitochondrial preparations]] in a wide variety of species, tissues and cell types. SUIT-001 gives information of the linear coupling control ([[LEAK respiration|''L'']]-[[Oxidative phosphorylation| ''P'']]-[[ET capacity| ''E'']]) with NADH linked-substrates ([[PM-pathway control state|PM]]). Moreover, the pathway control in ET state ([[NADH_Electron_transfer-pathway_state|N]], [[NS-pathway control state| NS]], [[FNS]], [[Succinate pathway control state| S]] and [[SGp-pathway control state| SGp]] pathways) can be evaluated by using this SUIT protocol. SUIT-001 can be extended with the CIV assay module. | |||

The SUIT-001 protocol in combination with SUIT-002 is specially designed to provide a common reference for comparison of respiratory control of mitochondrial preparations in a wide variety of species, tissues and cell types. SUIT-001 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 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:
- 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 S_E 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.
- + Harmonization with many SUIT protocols (up to step 5S).
- + Oct is added in ET state to avoid uncoupler effect with fatty acids.
- + If NS- and FNS-pathways are similar (NS_E ~ FNS_E), 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 substrate combination for maximum ET capacity (FNSGp) is not obtained in SUIT-001 in favour of measuring S_E.
- - Oct is not added in PBMC and PLT (SUIT-001 O2 ce-pce D004).
- - Lengthy duration of the experiment.
Compare SUIT protocols
- SUIT-001 O2 ce-pce D004 (SUIT-001 for permeabilized PBMC and PLT) differs from SUIT-001 O2 ce-pce D003 (general SUIT-001 for permeabilized cells) in the absence and presence of octanoylcarnitine, respectively.
- SUIT-002 (RP2): Harmonized SUIT protocol.
