The SUIT-002 O2 pce D007a protocol is the reference protocol 1 (RP1) specifically for PBMCs and PLTs. The main difference between the RP2 for PBMCs and PLTs and RP1 for other permeabilized cells (SUIT-002_O2_pce_D007) is the volume/concentration of the substrates and inhibitors. The SUIT-002 O2 pce D007a protocol in combination with SUIT-001_O2_pce_D004 provides a common reference for comparison of respiratory control of PBMC and platelets cells in a wide variety of species. SUIT-002 O2 pce D007a is specially designed to give information on F-pathway in OXPHOS state avoiding FAO overestimation in the presence of anaplerotic pathways. Moreover, the pathway control in OXPHOS state (F, F(N), FN, FNS, FNSGp pathways) and in ET state (FNSGp and SGp) can be evaluated by using this SUIT protocol. SUIT-002 O2 pce D007a 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.
- - 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 pce D007a (SUIT-002 for permeabilized PBMCs and PLTs) differs from SUIT-002 O2 pce D007 (general SUIT-002 for permeabilized cells) in the concentration and volume of the titrations.
- SUIT-001 O2 pce D004 (RP1): Harmonized SUIT protocol for PBMCs and platelets.
