Oligomycin
Description
Oligomycin (Omy) is an inhibitor of ATP synthase by blocking its proton channel (Fo subunit), which is necessary for oxidative phosphorylation of ADP to ATP (energy production). The inhibition of ATP synthesis also inhibits respiration. In OXPHOS analysis, Omy is used to induce a LEAK state of respiration.

Application in HRR
Omy: Oligomycin (Oligomycin from Streptomyces diastatochromogenes; mixture of oligomycins A, B, and C); Sigma O 4876, 5 mg; store at -20 °C; FW = 800.
Caution: Chemicals stored in the fridge or freezer should be allowed to reach room temperature before opening.
Preparation of 5 mM stock solution (dissolved in 99.9% ethanol):
- 1) Weigh 4 mg of Oligomycin into a 2 ml glass vial.
- 2) Dissolve in 1 ml Ethanol.
- 3) Divide into 0.2 ml portions or store in 2 ml glass vial and use subsamples during experiments to avoid contamination of the storage solution.
- 4) Store in glass vials (recommendation) at -20 °C.
Oxygraph-2k manual titrations: MiPNet09.12
- Titration volume: 1 µl using a 10 µl Syringe.
- Final conc. in 2 ml O2k-chamber: 2 µg/ml (2.5 µM).
