Method
Species / strain
- Species / strain / cell type:
- mouse lymphoma L5178Y cells
- Details on mammalian cell type (if applicable):
- Strain: 3.7.2C
Cells were cultured in Fischer's medium in a shaker incubator at 37°C in humidified 5% CO2 in air. Cultures were diluted daily to a cell density of approximately 3 x 10ˆ5 cells per ml. Each time a culture was used, it was checked for bacterial or fungal contamination.
Prior to use in the assay, L5178Y cells were treated with methotrexate to reduce the frequency of spontaneously occurring TK-/- cells. - Additional strain / cell type characteristics:

- Metabolic activation system:
- Aroclor S-9 metabolic activation

0, 1, 3, 7, 10, 33 µg/mL without S-9 - Vehicle / solvent:

- Details on test system and experimental conditions:
- - Test Material Exposure: Based on the data derived from the toxicity test, the test material was prepared so that the highest concentration would yield a percent total growth of approximately 10%. The test material was solubilized and diluted to produce evenly spaced dose levels which would yield approximately 90% total growth at the lowest dose. The test material was added to cells, both with and without metabolic activation and incubated for approximately 4 hours. Cells were then washed and placed into suspension culture at a density of 0.3 x 10ˆ6 cells/mL.
- Expression Time: In order for induced mutations to be expressed, the cells must undergo several divisions. This period is designated as the expression time. After the initial exposure to the test material the cells were incubated for 2 days and adjusted to 0.3 x 10ˆ6 cells/mL at 24 hours.
- Cloning: At the end of the expression period, a portion of the cells were plated in
(a) restrictive medium containing 3 ug/ml trifluorothymidine (TFT) which allowed only the TK-/- cells to grow, and
(b) non-restrictive medium which indicated cell viability.
The plates were incubated at 37°C + 1 C in humidified 5% CO2 in air for 10 days.
- Accumulation of Data: After the incubation period, both the mutagenicity (TFT restrictive medium) plates and the viability (non-restrictive medium) plates were scored for the total number of colonies per plate using an Artek 880 colony counter or by hand. The frequency of mutants induced by each test material dose was determined by comparing the average number of colonies in the mutagenicity plates to the average number of colonies in the corresponding viability plates. Induced mutagenic activity, if any, was quantified by comparing the mutant frequency of the treated plates to that of the control plates.
DETERMINATION OF CYTOTOXICITY
The test material was checked for toxicity with and without S-9 metabolic activation at dose levels of 1 ug/ml to 5000 µg/ml. No growth of the cell population was observed at >500 ug/ml with S-9 and > 100 ug/ml without S-9. Less severe toxicity was observed at 100 (+S-9) and 10 ug/ml (-S-9). Compound precipitate was present at 5000 ug/ml. - Evaluation criteria:
- Criteria for an Acceptable Mouse Lymphoma Screen: All the following criteria should be met for the mutagenicity screen to be considered valid:
- The mutant frequency of the appropriate positive control (either with or without S-9 activation) should be at least twice that of the appropriate negative (solvent) control.
- The spontaneous mutant frequency of the negative (solvents control should be in the range of 20 to 200 per 10ˆ6 cells.
- The plating efficiency of the negative (solvent) control should be at or above 50%.
- The test material should be tested to the level of approximately 10% total growth, or the limits of solubility, or to a high dose of 10 mg/ml. Test materials may be tested as slurries.
The following criteria must be met for the outcome of the Mouse Lymphoma Screen (either with or without S-9 metabolic activation) to be considered mutagenic:
The mutant frequency of one or more test material concentrations, with >10% total growth, is at least two times greater than that of the negative (solvent) control.
The following result must be met for the outcome of the Mouse Lymphoma Screen (either the with or without metabolic activation) to be considered non-mutagenic:
None of the mutant frequencies of any of the test material concentrations, with a survival of >=10% total growth, are two times greater than that of the negative (solvent) control.

Applicant's summary and conclusion
- Conclusions:
- Under the conditions tested, this material was considered to be nonmutagenic in this screen.
- Executive summary:
The test material was evaluated for gene mutation in the L5178Y TK+/-mutagenicity screen with and without S-9 metabolic activation at concentrations ranging from 1 ug/ml to 333 ug/ml. None of the cultures exhibited a mutant frequency which was two times that of the average mutant frequency of the negative (solvent) controls. Under the conditions tested, this material was considered to be nonmutagenic.
