Do you see fluctuations of O₂ slope negative following a pattern similar to the Peltier power, but without block temperature variation?

Placing the O2k under direct airflow of an air conditioning equipment may lead to disturbances in the O₂ slope negative.

+|''' How do I determine the optimal oligomycin concentration for my assay?'''<br>
-Background H<sub>2</sub>O<sub>2</sub> calibration refers to a set of H<sub>2</sub>O<sub>2</sub> titrations conducted after addition of respiration medium, DTPA, HRP, SOD and Amplex UltraRed to the O2k-chamber but before sample addition. This step is required 1) for the calculation of the theoretical chemical background fluorescence in our Excel analysis template, and 2) for the calculation of the sensitivity of the AmR assay, which serves as a quality control of the assay. <br>
+Perform the oligomycin titration test, and adjust your oligomycin concentration to minimize the inhibition of ET capacity. <br>
