- METHOD OF APPLICATION:
Bacteria from overnight cultures showing an optical density of at least 2.0 (measured at a wavelength of 600 nm) were used. 5 ml of the overnight cultures were added to tubes containing 25 ml Ames II Exposure medium and were gently mixed. After thorough pipetting bactiera suspension, test substance (or vehicle or control) and S9 mix (if applicable) were added. The 24-well plates were incubated at 37°C with shaking at 250 rpm for about 90 minutes. After this incubation period, 2.8 ml Ames II Reversion indicator medium (containing bromocresol purple) was pipetted to each well of the 24-well plate. The contents of each well of the 24-well plates were distributed in 50 μl aliquots over 48 wells of a 348-well Revertant Colony Selection plate (RCSP). The plates were sealed in plastic bags and incubated at 37°C in the dark. After 48 hours incubation each 48-well section of the RCSP were scored and the number of positive wells (yellow= high number of his+ revertants) were counted.
NUMBER OF REPLICATIONS: 48 wells in triplicate plates per dose or per control
DETERMINATION OF CYTOTOXICITY
- Method: beckground lawn, decrease in the number of yellow wells - Evaluation criteria:
- Evaluation was performed by the following comparisons/calculation:
- An increase in the mean number of positive wells in dose groups was compared to the mean value of the concurrent negative control (Evaluation factor 1 F).
- An increase in the mean of revertant wells in dose groups was calculated on the basis of the baseline data of the actual experiment (Evaluation factor 2 F). The baseline was derived from the mean spontaneous revertant number plus the value of standard deviation (mean+ SD) from the distribution of spontaneous data.
- An increase in the mean of revertant wells in dose groups was calculated on the basis of the baseline data of an experimental run (Evaluation factor 3 F). A run consists of a variable number of experiments generally testing different test substances together each using the same vehicle control. This leads to an accumulation of replicates for negative controls which was used to calculate the mean spontaneous reversion number for each run.
A test substance is considered mutagenic in this test system if more than a doubling of Evaluation factor 3 F is observed in at least one test group. This finding should be dose-dependent and/or reproducible.
