Viability of PBMCs irradiated (5, 10, and 15 Gy) in the absence or presence of fullerenol C₆₀(OH)₃₆ (50–150 mg/L) after 24-h-post-irradiation incubation (37 °C, 5% CO₂ atmosphere, 100% relative humidity). Preincubation with fullerenol lasted 1 h. The cells were stained with PI and calcein-AM (c-AM). Bars represent mean values with standard deviations. Asterisks are used to mark values that are statistically different in comparison with control values (* p < 0.05). All experiments were repeated 3–6 times.
