Method
- Target gene:
- S. typhimurium
Species / strain
- Species / strain / cell type:
- other: Salmonella typhimurium TA100, 98, 1535, 1537, 97
- Metabolic activation:
- with and without
- Metabolic activation system:
- rat liver S-9 mix
- Test concentrations with justification for top dose:
- 0, 33 - 2000 ug/plate
- Vehicle / solvent:
- The solvent of choice was distilled water, followed by dimethyl sulfoxide (DMSO), 95% ethanol, and acetone.
- Details on test system and experimental conditions:
- Salmonella typhimurium strains were obtained from Dr . Bruce Ames (University of California, Berkeley) and stored as recommended [Maron and Ames,
19831. Cultures were grown at 37°C overnight, with shaking, in Oxoid #2 broth (CWR, MIC), or in defined minimal medium supplemented with biotin (0.8 ug/ml) and histidine (40 ug/ml) (SRI). The phenotypes of the strains were analyzed at the time of their use in mutagenicity assays.
The S-9 (9,000 X g supernatant) fractions of Aroclor 1254-induced, male Sprague-Dawley rat and male Syrian hamster livers were prepared as described previously [Haworth et al ., 1983]. The S-9 mixes were prepared immediately prior to use and contained either 10% or 30% S-9; occasionally, 5% S-9 was also used. All chemicals were tested in the absence of metabolic activation, and with rat and hamster S-9 fractions.
