Structures of the tocopherols and the effect of mixed tocopherols (γTmT) on the growth of CL13 cells in culture. Effects on cell growth and viability were assessed using the MTT assay. Cells were treated for 2 or 5 d with γTmT in serum-complete cell culture medium. Each point represents the mean of n = 18. Error bars represent the SEM. For points were no error bar is visible, this indicates that the error is smaller than the size of the point.
