Strengths and limitations
- + Reasonable duration of the experiment.
- + Simple protocol to evaluate the oxygen dependence of H2O2 production.
- - Measurements with Amplex UltraRed assay cannot be carried out with liver homogenate.
- - H2O2 production can be studied in two different states, LEAK and OXPHOS.
- - Reoxygenation and nitrogen injection could lead to bubble formation in the O2k-Chamber
