Constituent 1
Method
- Target gene:
- Tester strains TA98 and TA1535 are reverted from histidine dependence (auxotrophy) to histidine independence (prototrophy) by frameshift mutagens. Tester strain TA1535 is reverted by mutagens that cause basepair substitutions. Tester strain TA100 is reverted by mutagens that cause both frameshift and basepair substitution mutations. Specificity of the reversion mechanism in E. coli is sensitive to base-pair mutations, rather than frameshift mutations (Green, MHL, and Muriel WJ (1976).

- Details on test system and experimental conditions:
- METHOD OF APPLICATION: in agar (plate incorporation); preincubation
The test system was exposed to the test article via the plate incorporation methodology originally described by Ames et al. (1975) and updated by Maron and Ames (1983). In the conformatory assay, the test system was exposed to the test article via the preincubation methodology described by Yahagi et al. (1977).

DURATION
- Exposure duration: The test article dilutions were prepared immediately before use. In the plate incorporation method, one-half (0.5) milliliter of S9 or Sham mix, 100 µL of tester strain and 50 or 25 µL of vehicle or test article were added to 2.0 mL of molten selective top agar at 45+/- 2°C. After vortexing, the mixture was overlaid onto the surface of 25 mL of minimal bottom agar. In the preincubation method, one-half (0.5) milliliter of S9 or sham mix, 100 µL of tester strain and 25 µL of vehicle or test article were added to 13 x 100 mm glass culture tubes pre-heated to 37 +/- 2°C. After vortexing, these mixtures were incubated without shaking for 60 +/- 2 minutes at tube and the mixture was vortexed and overlaid onto the surface of 25 mL of minimal bottom agar. When plating the positive controls, the test article aliquot was replaced by a 50 µL aliquot of appropriate positive control. After the overlay had solidified, the plates were inverted and incubated for approximately 48 to 72 hours at 37 +/- 2°C. Plates that were not counted immediately following the incubation period were stored at 4+/- 2°C until colony counting could be conducted.
The condition of the bacterial background lawn was evaluated for evidence of test article toxicity and precipitate by using a dissecting microscope. Toxicity and degree of precipitation were scored relative to the vehicle control plate.
Background bacterial evaluation code:
1 = normal
2 = slightly reduced
3 = Moderately reduced
4 = Extremely reduced
5 = Absent
6 = Oscured by precipitate
SP = Slight precipitate
MP = Moderate precipitate
HP = Heavy precipitate
Revertant colonies for a given tester strain and activation condition were counted either entirely by automated colony counter or entirely by hand unless the assay was the preliminary toxicity assay or the plate exhibited toxicity. Plates with sufficient test article precipitate to interfere with automated colony counting were counted manually.
NUMBER OF REPLICATIONS: All dose levels of test article, vehicle controls and positive controls were plated in triplicate.
DETERMINATION OF CYTOTOXICITY
- Method: relative total growth: A minimum of three non-toxic dose levels will be required to evaluate assay data. A dose level is considered toxic if it causes a > 50% reduction in the mean number of revertants per plate relative to the mean vehicle control value (this reduction must be accompanied by an abrupt dose-dependent drop in the revertant count) or a reduction in the background lawn. In the event that fewer than three non-toxic dose levels are achieved, the affected portion of the assay will be repeated with an appropriate change in dose levels. - Evaluation criteria:
- For the test article to be evaluated positive, it must cause a dose-dependent increase in the mean revertants per plate of at least one tester strain with a minimum of two increasing concentrations of test article. Data sets for strains TA 1535 and TA 1537 were judged positive if the increase in mean revertants at the peak of the dose response is equal to or greater than three times the mean vehicle control value. Data sets for strains TA98, TA100 and WP2 uvrA and WP2 were judged positive if the increase in mean revertants at the peak of the dose response is equal to or greater than two times the mean vehicle control value.
- Statistics:
- For each replicate plating, the mean and standard deviation of the number of revertants per plate were calculated and are reported.

Any other information on results incl. tables
Mutagenicity assay:
In Experiment B1, the initial mutagenicity assay, no positive responses were observed with any of the tester strains in the presence and absence of S9 activation.
In Experiment B2, the confirmatory assay, no positive responses were observed with tester strains TA98, TA100, TA1535, TA1537 and WP2 uvrA (pKM101) in the presence of S9 activation and with the tester strains TA1535, TA1537 and Wp2 (pKM101) in the absence of S9 activation. Due to excessive toxicity, tester strain WP2 uvrA (pKM101) in the presence of S9 activation were not evaluated but were retested in Experiment B3. To clarify the response, tester strain TA100 in the presence of S9 activation was retested in Experiment B3.
In experiment B3, no positive responses were observed with tester strain WP2 uvrA (pKM101) in the presence of S9 activation and tester strains TA98, TA100 and WP2 uvrA (pKM101) in the absence of S9 activation.
All criteria for a valid study were met as described in the protocol.
