Gamma Radiation-Induced Damage in the Zinc Finger of the Transcription Factor IIIA

Figure 2

Restoration of the binding capacity of irradiated transcription factor IIIA (TFIIIA) with the internal control region (ICR) by DL-dithiothreitol (DTT) solution. (a) Band of binding of gamma-irradiated TFIIIA (1000 Gy) with the ICR after irradiated TFIIIA was incubated with different concentrations of DTT (0.05 mM, 0.1 mM, 0.2 mM, 0.5 mM, and 1.0 mM). (b) Integral optical density (IOD) of the corresponding binding.
