Abstract |
The traditional way to characterize a complex sample has been by chemical analysis to identify the individual components. However, unknown or overlooked mutagens or carcinogens may remain undetected by this method. In recent years a combination of chemical analysis and mutagenicity testing has been applied successfully to samples to provide a more complete assessment of mutagens in complex mixtures. The authors recently reported a new technique whereby complex samples were separated on thin-layer chromatography plates, and their mutagenic effect was registered directly on the developed plate by the Salmonella mutagenicity assay. This combined fractionation/bioassay scheme offers several advantages. Components of complex samples can be separated by one- or two- dimensional chromatography prior to exposure to the bacteria. By using the TLC plates, toxic compounds or components exhibiting synergistic/antagonistic effects may be separated from the mutagens and detected independently. |
