Fig 2. Measurement of the intracellular ROS intensity of controls and ERW using BES-H₂O₂ probe.

MQ, MilliQ water; FW, filtered pure water; +Mixed gas, H₂, O₂ and N₂ mixed gas was bubbled through water to obtain DO and DH concentrations that are equal to those of LV4. The pH was also adjusted using sodium hydrate.; LV4, ERW at electrolysis level 4. NAC, 5 mM N-acetyl cysteine. *a, *b and *c indicate p values of < 0.01 when compared with the value for H₂O₂-treated MQ, FW and +Mix gas of FW, respectively.
