It was suggested that to deprotonate L-012 by one-electron oxidation to its radical form, the presence of strong oxidants, in addition to H2O2, is highly recommended. Therefore, the inclusion of HRP is also highly recommended. Moreover, it was mentioned that the presence of superoxide ion alone may not be sufficient to drive the reaction forward. In the event that no reaction was detected, it is highly recommended to titrate up the concentration of H2O2 and HRP, as well as include xanthine oxidase and hypoxanthine to help drive this reaction.

Application
L-012 has been used as a probe in a bioluminescent assay for the determination of the reactive oxygen species (ROS) levels in the isolated mouse lungs.[1]
Biochem/physiol Actions
L-012 is a luminol analog and a widely used reactive oxygen and nitrogen species (RONS; ROS & RNS) chemiluminescence (CL) probe both in cultures and in animals in vivo. L-012 displays significantly higher CL yield and sensitivity than luminol, lucigenin and MCLA. Instead of reacting with superoxide anion (O2−) directly, L-012 (LumH2) is converted via a one-electron oxidation (catalyzed by peroxidase in the presence of H2O2) to the LumH· radical form, which then reacts with oxygen (O2) to yield O2− and L-012 quinone (q-Lum). The O2− in turn reacts with the LumH· radical, leading eventually to an endoperoxide that decomposes to emit luminescence. To a less extend, H2O2 can also react with q-Lum to yield luminescence. Although not specific to NADPH oxidase-derived RONS, L-012 is also commonly used for screening NADPH oxidase inhibitors.
