Method
Species / strain
- Species / strain / cell type:
- S. typhimurium TA 100
- Metabolic activation:
- with and without
Controls
- Positive controls:
- yes
- Remarks:
- The following mutagenic substances were used as positive controls: 6.2.1 4-Nitro1,2-phenylene diamine 4-Nitro-1,2-phenylene diamine, C6H7N3〇2; CAS-No.: 99-56-9
- Details on test system and experimental conditions:
- General Preparation: Per strain and dose, four plates with and four plates without S9 mix were used. The test item solutions were prepared and membrane filtered in order to accomplish sterility.
Top agar basis was melted in a microwave oven, after melting 10 mL of histidine-biotin-solution 0.5mMol per 100 mL basis was added and the bottle was placed in the water bath at 43°C.
Plate incorporation method: the following materials were slightly vortexed in a test tube and poured onto the selective agar plates:
• 100 µL test suspension at each dose level, solvent (negative control) or reference mutagen solution (positive control)
• 500 µL S9 mix or phosphate buffer
• 100 µL bacteria suspension
• 2200 µL overlay agar
The plates were closed and left to harden for a few minutes, then inverted and placed in the dark incubator at 37°C.
Pre incubation method: The following materials were gently vortexed in a test tube and incubated at 37°C for 20 minutes:
• 100 µL test suspension at each dose level, solvent (negative control) or reference mutagen solution (positive control)
• 500 µL S9 mix or phosphate buffer
• 100 µL bacteria suspension
After pre-incubation 2000µL overlay agar (top agar) was added, the tube was gently vortexed and the mixture was poured onto the selective agar plate.
