Dependence of Hb redox state and ligand binding on pDNA degradation. The different forms of Hb were incubated in presence of pDNA at 37 °C for 12 h and the percentage of remaining sc pDNA was determined. Control (black), CO (blue), oxy (red) and ferric (pink) form of Hb (10 µM) was incubated with pDNA and samples were taken at intervals of 2 h. CO-Hb was less reactive compared to oxy and metHb. Data present mean±S.D., n=3. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.).
