Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
positive with metabolic activation only for strain TA100
The Ames test indicated that there was no activation without metabolic activation. With metabolic activation, one strain showed positive results (TA100) while all other strains were negative.
