Fluorescence emission spectra of the EtBr-DNA complex when increasing the amount of GSH with a total gamma-irradiation dosage of 1,252 Gy. a [EtBr] = 60.0 μM only, b [EtBr] = 60.0 μM + [DNA] = 60.0 μM, c [EtBr] = 60.0 μM + [DNA] = 60.0 μM; with total gamma-irradiation dosage of 1,252 Gy, d 10.0 μM GSH, e 20.0 μM GSH, f 30.0 μM GSH, g 40.0 μM GSH, h 50.0 μM GSH, and i 60.0 μM GSH.
