FIG. 3.

Effect of storage time on Prx-2 recovery after H₂O₂ exposure with added glucose. Human RBCs stored for 7 (□) or 35 days (▼) were exposed to 10 μM H₂O₂ for 5, 15, 30, or 60 min in the presence of glucose (5 mM) and Prx-2 oxidation was measured as described in Materials and Methods section. Data show values normalized to maximal levels of oxidized Prx-2 (at 5 min) and are mean±SEM (n=3). *p<0.05 and ^#p<0.01 by two-way ANOVA with Bonferroni post hoc test.
