Rotenone

Description

Rotenone is an inhibitor of Complex I (CI) and thus inhibits NADH oxidation. It inhibits the transfer of electrons from iron-sulfur centers in CI to ubiquinone via binding to the ubiquinone binding site of CI. See also Complex II-linked substrate state, S(Rot).

Abbreviation: Rot

Reference: Gnaiger 2014 MitoPathways, MiPNet09.12, MiPNet03.02






MitoPedia topics: Inhibitor 

Application in HRFR

Rot: Rotenone (C23H22O6); Sigma R 8875, 1 g, store commercial stock at RT; FW = 394.42 (β‰₯ 95%).
Caution: Very toxic and light sensitive (store solution in a dark glass vial)..


Preparation of 1 mM stock solution (dissolved in 99.9% ethanol)
  1. Weigh 0.39 mg of rotenone and dissolve in 1 ml of ethanol absolute (99.9%).
  2. Divide into 100 Β΅l aliquots (use dark glass vials).
  3. Store frozen at -20 Β°C.


O2k manual titrations MiPNet09.12 O2k-Titrations
  • Titration volume: 1 Β΅l using a 10 Β΅l syringe (2 ml O2k-chamber).
  • Final concentration: 0.5 Β΅M.
