- Currently Answered Questions from the »Oroboros Ecosystem Agenda«
May 2020
- May-11 Th
Do you know how to avoid underestimating/overestimating your respiratory fluxes? Measuring steady states with high-resolution respirometry is the key to obtaining correct values.
- Learn more about steady states measured with high-resolution respirometry: performance and mark setting for data analysis. - »Steady state«
- May-04 Mo
Do you load the correct instrumental background correction accordingly to your range of experimental O2 levels? - See how to perform the instrumental background test. - » O2 background correction in DatLab« and » Instrumental oxygen background«
Apr 2020
- Apr-27 Mo
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«
- Apr-20 Mo
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«
- Apr-14 Mo
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«
- Apr-07 Mo
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«
- Apr-02 Mo
Did you know that you can edit the background parameters in the 'O2 analysis template DL7.4? - Do you want to search the best SUIT protocol for your research questions? - Use the SUITbrowser: »SUITbrowser«

- Mar-23 Mo
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«
- Mar-11 We
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«

- New A damaged OroboPOS-Holder may cause medium to leak from the O2k-Chamber.
- See how you can check that the two blue OroboPOS-Holders are intact. - »O2k-OroboPOS-Holder«
- New A damaged OroboPOS-Holder may cause medium to leak from the O2k-Chamber.
