Figure 2

Relative cytotoxicity of ascorbic acid on cancer and benigne cells. Shown are the EC50 values of different cell lines for an ascorbic acid exposure time of 14 h and an ascorbic acid free culture time of 34 h. Cell viability was measured with the crystal violet assay at the end of culture. The results shown are representative for 3 independent analyses.
