Method
- Target gene:
- Tester strains TA98 and TA1537 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 basepair substitution mutations, rather than frameshift mutations (Green and Muriel, 1976).

- Details on test system and experimental conditions:
- The initial toxicity-mutation assay was used to establish the dose-range for the confirmatory mutagenicity assay and to provide a preliminary mutagenicity evaluation. Vehicle control, positive controls and eight dose levels of the test substance were plated, two plates per dose, with overnight cultures of TA98, TA100, TA1535, TA1537 and WP2 uvrA on selective minimal agar in the presence and absence of Aroclor-induced rat liver S9.
The confirmatory mutagenicity assay was used to evaluate and confirm the mutagenic potential of the test substance. Five dose levels of test substance along with appropriate vehicle control and positive controls were plated with overnight cultures of TA98, TA100, TA1535, TA1537 and WP2 uvrA on selective minimal agar in the presence and absence of Aroclor-induced rat liver S9. All dose levels of test substance, vehicle control and positive controls were plated in triplicate.
After the agar overlay had solidified, the plates were inverted and incubated for 48 to 72 hours at 37±2°C. Plates that were not counted immediately following the incubation period were stored at 2-8°C until colony counting could be conducted. - Evaluation criteria:
- For the test substance to be evaluated positive, it must cause a dose-related increase in the mean revertants per plate of at least one tester strain over a minimum of two increasing concentrations of test substance. Data sets for tester strains TA1535 and TA1537 were judged positive if the increase in mean revertants at the peak of the dose response was greater than or equal to 3.0-times the mean vehicle control value. Data sets for tester strains TA98, TA100 and WP2 uvrA were judged positive if the increase in mean revertants at the peak of the dose response was greater than or
equal to 2.0-times the mean vehicle control value.
An equivocal response is a biologically relevant increase in a revertant count that partially meets the criteria for evaluation as positive. This could be a dose-responsive increase that does not achieve the respective threshold cited above or a non-dose responsive increase that is equal to or
greater than the respective threshold cited. A response was evaluated as negative, if it was neither positive nor equivocal. - Statistics:

Applicant's summary and conclusion
- Conclusions:
- All criteria for a valid study were met as described in the protocol. The results of the Bacterial Reverse Mutation Assay indicate that, under the conditions of this study, the test material did cause positive mutagenic responses with tester strains TA100 and TA1535 in the presence and absence of Aroclor-induced rat liver S9 and tester strain WP2 uvrA in the presence of Aroclor-induced rat liver S9. Therefore, the test substance was concluded to be positive in this assay.
- Executive summary:
The test substance, 1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, oligomeric reaction product with (chloromethyl)oxirane was tested in the Bacterial Reverse Mutation Assay using Salmonella typhimurium tester strains TA98, TA100, TA1535 and TA1537 and Escherichia coli tester strain WP2 uvrA in the presence and absence of Aroclor-induced rat liver S9. The assay was performed in two phases, using the plate incorporation method. The first phase, the initial toxicity-mutation assay, was used to establish the dose-range for the confirmatory mutagenicity assay and to provide a preliminary mutagenicity evaluation. The second phase, the confirmatory mutagenicity assay, was used to evaluate and confirm the mutagenic potential of the test substance. Dimethyl sulfoxide (DMSO) was selected as the solvent of choice based on the solubility of the test substance and compatibility with the target cells. The test substance formed a clear solution in DMSO at approximately 500 mg/mL, the maximum concentration tested in the solubility test conducted at BioReliance. In the initial toxicity-mutation assay, the maximum dose tested was 5000 μg per plate; this dose was achieved using a concentration of 100 mg/mL and a 50 μL plating aliquot. The dose levels tested were 1.5, 5.0, 15, 50, 150, 500, 1500 and 5000 μg per plate. Positive mutagenic responses (ranging from 4.3- to 68.6-fold maximum increases) were observed with tester strains TA100 and TA1535 in the presence and absence of S9 activation and tester strain WP2 uvrA in the presence of S9 activation. Neither precipitate nor toxicity was observed. Based on the findings of the initial toxicity-mutation assay, the maximum dose plated in the confirmatory mutagenicity assay was 5000 μg per plate. In the confirmatory mutagenicity assay, the dose levels tested were 50, 150, 500, 1500 and 5000 μg per plate. Positive mutagenic responses (ranging from 4.2- to 93.9-fold maximum increases) were observed with tester strains TA100 and TA1535 in the presence and absence of S9 activation and tester strain WP2 uvrA in the presence of S9 activation. Neither precipitate nor toxicity was observed. Under the conditions of this study, the test material was concluded to be positive in the Bacterial Reverse Mutation Assay.
