Figure 4. Impact of antioxidants on melatonin enhancement of DCFH2 and DCFH2-DA photooxidation.

Figure 4

A) Fluorescence of DCFH2 (10 µM), MEL (1 mM), H2O2 (10 µM) alone or in combination under light for 300 second. B) Evaluation of fluorescence of DCFH2 (10 µM) with CAT (200 U), SOD (200 U), NAC (10 mM) and AA (10 mM) with or without supplementation of MEL (1 mM) under light for 300 seconds. C) Evaluation of fluorescence of DCFH2-DA (100 µM) with CAT (200 U), SOD (200 U), NAC (10 mM) and AA (10 mM) with or without supplementation of MEL (1 mM) under 30 min seconds of light exposure.
