Description
Sodium azide is an inhibitor of Complex IV/cytochrome c oxidase (CIV, COX, CcO).
Abbreviation: Azd
Reference: MiPNet03.02
Application in HRR
- Azd: Azide (Sodium azide; NaN3), Sigma-Aldrich: S2002, store at RT, CAS: 26628-22-8, M = 65.01 gยทmol-1
- Hazard statements: H300, H310, H330, H373, H410; fatal if swallowed, fatal in contact with skin, fatal if inhaled, may cause damage to organs through prolonged or repeated exposure (brain), very toxic to aquatic life with long-lasting effects
- Azd: Azide (Sodium azide; NaN3), Sigma-Aldrich: S2002, store at RT, CAS: 26628-22-8, M = 65.01 gยทmol-1
- 2021-03: Preparation instructions were updated to take the volume of the solute into account (see Volume of the solute). The concentrations prepared following the former instructions (see Discussion section) are sufficiently high for SUIT protocol titrations.
- Preparation of 4 M storage and stock solution (1 mL, dissolved in H2O) for 2-mL O2k-chamber:
- Weigh 260 mg of sodium azide.
- Dissolve in 900 ยตL H20.
- Divide into 0.5 mL portions.
- Store at -20 ยฐC.
- ยปO2k manual titrations MiPNet09.12 O2k-Titrations
- Titration volume (2-mL O2k-chamber): โฅ50 ยตL using a 100 ยตL Hamilton syringe.
- Final concentration: โฅ100 mM.
- Preparation of 2 M stock solution (dissolved in H2O) for 0.5-mL O2k-chamber:
- Take 400 ยตL of the 4 M stock solution.
- Add 400 ยตL H2O.
- ยปO2k manual titrations MiPNet09.12 O2k-Titrations
- Titration volume (0.5-mL O2k-chamber): โฅ25 ยตL using a 100 ยตL Hamilton syringe.
- Final concentration: โฅ100 mM.
