In fact in terms of sensitivities induced mutant frequencies at the tk locus were found to be greater than those seen at the hprt locus under the same treatment conditions (Clive et al 1990).

From these estimates it appears that the SH-SY5Y cells are the most sensitive of those examined to the cytotoxic and possibly cytostatic effect of MSE. Based upon my estimation of 42% MIT-like compound in MSE extract the SHSY5Y cell IC50 for MSE is equal to 9. M MIT-like compound. This is not dissimilar to the experimentally determined IC50 for pure MIT of 7. To assess the long-term effect of MSE on surviving cells after acute treatment a clonogenicity assay was performed after 24 hr treatment on HEK 293 and SHSY5Y cells. Additional clonogenicity assays using chloroform and combinations of chloroform and MSE were also carried out to determine whether potential chloroform contamination of MSE could influence cytotoxicity. MSE were unable to generate colonies.
