The effect of chelator concentration on the proliferation of SK-N-MC neuroepithelioma cells.

Cells were incubated in the presence and absence of the chelators (0-12.5 μM) for 72 hours at 37°C. After this incubation period, cellular density was measured with the MTT assay (see “Materials and methods”). Each data point represents the mean of 2 replicates in a typical experiment of 3 experiments performed.
