Template:SUIT text D024

From Bioblast

The SUIT-011 O2 pfi D024 protocol is designed to study physiologically relevant maximum mitochondrial respiratory capacity (OXPHOS with NS substrates) and coupling/pathway control states. SUIT-011 gives information of the linear coupling control (L- P) with NADH linked-substrates (GM). GM and PM yield practically identical fluxes in human skeletal muscle fibers. However, PM is the superior alternative to GM, since the fractions of the N-pathway is lower and of the S-pathway is higher with GM compared to PM. PM, therefore, yields a more sensitive assay for the diagnosis of injuries in the N-linked pathway (compare SUIT-001 and SUIT-004). Moreover, SUIT-011 allows the evaluation of the coupling control state (P- E) with NADH and succinate linked-substrates (NS) and the pathway control in OXPHOS (NS) and ET state (NS and S). SUIT-011 can be extended with the CIV assay module.
