Cyanide

Description

Cyanide (usuall added as KCN) is a competitive inhibitor of cytochcrome c oxidase (CIV). Inhibition is reversed by pyruvate and high oxygen levels.

Abbreviation: KCN

Reference: MiPNet09.12


MitoPedia methods: Respirometry 


MitoPedia topics: Inhibitor 

Application in HRR

Kcn(KCN): Fluka 60178, 100 g, store at R.T.; FW = 65.12

Caution: KCN is photosensitive and hygroscopic; HCN is volatile and very toxic! Prepare the solution fresh everyday!


Preparation of 1 M stock solution (dissolved H2O):

1) Weigh 13 mg of Potassium cyanide
2) Dissolve in 0.2 ml H2O
3) The pH of the solution may be very alkaline - adjust to physiological pH with HCl


Oxygraph-2k Manual Titrations: MiPNet09.12

  • Titration volume: 2 Β΅l using a 10 Β΅l syringe
  • Final conc. in 2 ml O2k-chamber: 1 mM
