Figure 4From: Mechanism-based genotoxicity screening of metal oxide nanoparticles using the ToxTracker panel of reporter cell linesInduction of the ToxTracker assay by metal ions. mES cells were exposed to CuSO4 (25 – 1000 μM), ZnSO4 (50 – 1000 μM), NiCl2 (50 – 1000 μM) for 24 h. GFP induction and cell viability were determined with flow cytometry. Results are presented as mean ± standard deviation of three independent experiments.Back to article page
