Substrate-uncoupler-inhibitor titration
Description
Mitochondrial SUIT protocols are used with mt-preparations to study respiratory control in a sequence of coupling and substrates states induced by multiple titrations.
Abbreviation: SUIT
Reference: MiPNet12.12, MiPNet09.12, Gnaiger_2007_MitoPathways, Gnaiger_2009_IJBCB
MitoPedia topics: "Respiratory state" is not in the list (Enzyme, Medium, Inhibitor, Substrate and metabolite, Uncoupler, Sample preparation, Permeabilization agent, EAGLE, MitoGlobal Organizations, MitoGlobal Centres, ...) of allowed values for the "MitoPedia topic" property.
Respiratory state"Respiratory state" is not in the list (Enzyme, Medium, Inhibitor, Substrate and metabolite, Uncoupler, Sample preparation, Permeabilization agent, EAGLE, MitoGlobal Organizations, MitoGlobal Centres, ...) of allowed values for the "MitoPedia topic" property.
SUIT protocols have been developed for the first time on the basis of high-resolution respirometry, since their application depends critically on long-term stability of the polarographic oxygen sensor (experiments may be extended over 1 to 2 hours), highly diluted sample to avoid fast oxygen depletion in the closed chamber, and the possibility for re-oxygenations to extend measurement of oxygen flux. The mitochondrial preparation must be stable over such experimental periods of time, hence specific mitochondrial respiration media (MiR05: Gnaiger_2000_MitoInTheCold; MiR06) have been developed to maintain respiratory capacity during application of mitochondrial SUIT protocols at physiological temperature (Gnaiger_2007_MitoPathways).
