Effect of melatonin on HUVEC cell viability. (a) MTT assay shows that PolyRad is non-toxic at concentrations of \(\le \) 0.01 mg/ml. Data represents mean and standard deviation of three independent experiments. (b) Calcein AM (green fluorescence) and EthD-1 (red fluorescence) live/dead assay stain live and dead HUVEC, respectively after 0.01 mg/ml of PolyRad incubation.
