Figure 5

Background hydrogen peroxide production and oxygen consumption by EGCG. (a) H₂O₂ production detected by Amplex Red (–7); (b) oxygen consumption during H₂O₂ measurement (); (c) oxygen consumption in plain K-medium (–8). The background measurements in a and b were performed using two different fluorometry and oxygen sensors; measurements in (c) were performed using six different oxygen sensors. HRP: horseradish peroxidase.
