Description
Abbreviation: O2 dependence of H2O2 production ce
Reference: A SUIT-013
SUIT number: D023_ce1
O2k-Application: AmR
This protocol has been designed to study the oxygen dependence of H2O2 production in living cells. SUIT-013 AmR ce D023 is suitable for demonstration of the oxygen dependence in bakerΒ΄s yeast. For further details see: Komlodi 2021 MitoFit AmR-O2. The respiration medium has to be chosen carefully, since the Amplex UltraRed assay leads to artefact formation with the components of the buffer.

Strengths and limitations
- To study the inhibitory effect of the AmR assay on the respiration using living cells, the following protocols are recommended: SUIT 003 AmR ce D058 with AmR and SUIT 003 AmR ce D059 with carrier titration as a control. These two protocols have to be done in parallel.
- + Reasonable duration of the experiment.
- + Quick demonstration of the oxygen dependence of H2O2 production.
- + No externally added substrates are required with yeast.
