Migrated to IUCLID6: 100 μg/plate, dissolved in DMSO for TA 1537
- Details on test system and experimental conditions:
- METHOD OF APPLICATION: in agar (plate incorporation); preincubation
PROCEDURE
- The experimental procedure of the standard plate test (plate incorporation method) was based on the method of Ames et al. (Mut. Res., 31, 347 - 364, 1975)
- The experimental procedure of the Preincubation Test was based on the method described by Yahagi et al. (Mut. Res., 48, 121 - 130, 1977) and Matsushima et al (In: Norpoth, K.H. and R.C. Garner, Short-Term Test Systems for Detecting Carcinogens. Springer Verlag Berlin, Heidelberg, New York, 1980) - Evaluation criteria:
- - The test chemical is considered positive in this assay if a dose-related and reproducible increase in the number of revertant colonies, i.e. about
doubling of the spontaneous mutation rate in at least one tester strain either without S9 mix or after adding a metabolizing system.
- A test substance is generally considered non-mutagenic in this test if the number of revertants for all tester strains were within the historical negative control range under all experimental conditions in at least two experiments carried out independently of each other.
