Any other information on results incl. tables
All positive control groups showed significantly increased mutation frequencies which demonstrate the sensitivity of the test system.
No toxicity of the test substance to the bacteria was observed up to 5000 μg per plate.
In none of the concentrations tested and with none of the strains used an increase of the mutation frequency to more than the threshold values (250 % of the controls for strains TA98 and TA1535, 167 % of the controls for strains TA97a, TA100 and TA102) was obtained. Metabolic activation did not change these results.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
According to the results obtained in this study, "Fam-stage-1" is non-mutagenic in the Ames test with the strains TA97a, TA98, TA100, TA102 and TA1535 with and without an external metabolising system up to 5000 μg/plate, which is the limit concentration for this kind of test.
