Do you select the appropriate marks for the instrumental background correction when planning to apply them to a protocol with a high O₂ regime?

- To obtain an accurate O₂ background correction, you must select the marks that correspond to your range of experimental O₂ levels. - » O2 Background correction - troubleshooting«

Did you know that some substrates alone cannot maintain a stable mitochondrial respiratory flux in OXPHOS?

- Unstable respiratory fluxes in OXPHOS might be due to substrates limitation. - » Pyruvate - troubleshooting«

Why are the oxygen levels different between chambers prior to my experimental run?

- After switching on the O2k, air calibration has to be performed; otherwise the displayed concentrations may deviate from accurate concentrations. - » Oxygen calibration - troubleshooting«

Did you know that you can edit the background parameters in the 'O₂ analysis template DL7.4?

- If you did not apply a finally evaluated O2 background correction to your experimental DatLab file, you can edit the O2 background parameters directly in the O2 analysis template DL7.4 for completion of Oxygen flux analysis - DatLab 7.4. - »SUIT: Browse DL-Protocols and templates«

Do you know that you can use the Titration-Injection microPump (TIP2k) to perform an instrumental O₂ background on the O2k-sV-Module?

- (1) By adjusting the dithionite concentration to 2.5 mM, the instrumental O₂ background can be performed with the "BG Feedback" settings. - »O2k-sV-Module«
- (2) By adjusting the TIP2k setup with specific settings for the O2k-sV-Module, the instrumental O₂ background can be performed in the O2k-sV-Module. - »O2k-sV-Module«

Do you change the slope smoothing to 20 while running experiments with biological sample?

- While running your experiment, especially during uncoupler titrations, it is important to decrease the slope smoothing in order to have a faster visualization of the titrations effect on respiration. - »Slope smoothing«
