DNA damage in Medicago sativa cells in suspension cultures. DNA damage in cell suspension cultures treated with 0, 10, 50 and 100 nM MPA-CdSe/ZnS QD at room temperature for 48 hours or at 50°C for 20 minutes, under alkaline unwinding and neutral electrophoresis (A/N), under neutral incubation and neutral electrophoresis (N/N), and also by incubation with lesion-specific FPG or EndoIII enzymes. Results are expressed as mean values with the standard deviation. One –way ANOVA P < 0.0001. Values with different letters are significantly different at p ≤ 0.01 with Tukey test.
