Materials and methods
Test guideline
- Guideline:
- other: NTP protocol
- Principles of method if other than guideline:
- In the standard protocol (preincubation) for conducting the Ames assay, a test tube containing a suspension of one strain of Salmonella typhimurium plus S9 mix or plain buffer without S9, is incubated for 20 minutes at 37º C with the test chemical. Control cultures, with all the same ingredients except the test chemical, are also incubated. In addition, positive control cultures are prepared; these contain the particular bacterial tester strain under investigation, the various culture ingredients, and a known potent mutagen. After 20 minutes, agar is added to the cultures and the contents of the tubes are thoroughly mixed and poured onto the surface of Petri dishes containing standard bacterial culture medium. The plates are incubated, and bacterial colonies that do not require an excess of supplemental histidine appear and grow. These colonies are comprised of bacteria that have undergone reverse mutation to restore function of the histidine-manufacturing gene. The number of colonies is usually counted after 2 days.

Applicant's summary and conclusion
- Conclusions:
- The sample was tested for gene mutation in the genome of Salmonella typhimurium. Two strains were used, TA 98 and TA 100 - delegating different types of mutations. The sample was diluted with water. The experiments were performed with and without metabolic activation by rat and hamster liver. The sample was mutagenic to strain TA 98 and TA 100 with and without metabolic activation.
- Executive summary:
The sample was tested for gene mutation in the genome of Salmonella typhimurium., in strains TA 98 and TA 100, with and without metabolic activation by rat and hamster liver. The sample was mutagenic to strain TA 98 and TA 100 with and without metabolic activation.
Similar substance 07 could be considered as not mutagenic.
