Formation and Detection of Highly Oxidized Hemoglobin Forms in Biological Fluids during Hemolytic Conditions

Figure 2

Formation of oxidized Hb forms in hydrogen peroxide-induced oxidation of Hb and metHb. (a) Purified human Hb and (b) metHb (60 μmol/L heme) were oxidized with different concentrations of H2O2 (125, 250, and 500 μmol/L) for 10 minutes at 37°C. Concentrations of different redox states of Hb were determined by analysis of the visible spectra and the presence of different redox states of Hb as a percentage of total heme was calculated. The bar graph shows from 3 independent experiments. values were calculated using one-way ANOVA followed by Tukey’s multiple comparison analysis. , , .
