SUIT 9 is a short protocol for simultaneous determination of O2 flux and the rate of H2O2 production (H2O2 flux) on isolated mitochondria,tissue homogenate (except of liver) and permeabilized cells. Succinate (S) supports the reverse electron transfer (RET) initiated H2O2 production in the LEAK state. Addition of ADP decreases H2O2 flux due to depolarization of the mitochondrial membrane. Pyruvate (P) supports NADH-pathway (N), and usually in the presence of ADP it does not increase further the H2O2 flux. Antimycin A (Ama) inhibits Complex III (CIII) and results in the elevation of the H2O2 flux. The sensitivity of the Amplex UltraRed® assay (for determining H2O2 production) is changing over the experimental time and upon addition of chemicals. To correct H2O2 flux for the sensitivity changes several H2O2 calibration steps are done during the experiment. The measurement is carried out in MiR05-Kit at 37 °C. For O2-Application, choose SUIT-9 O2 mt D15; for O2 and H2O2 measurements (AmR), choose: D21_1S;2D;3P;4Rot;5Ama.
