Assessment of PBMCs viability in response to H₂O₂ treatment. Cells were incubated with increasing concentrations of H₂O₂ (50 μM, 100 μM, 250 μM, and 500 μM) for 2 h and cell viability was determined by MTT assay. The MTT assay was performed in triplicate and data are reported from the mean of triplicates. Data are expressed as means ± SEM. .
