- CAT-Acid Chloride was evaluated for mutagenic activity in the Ames test. A standard plate
incorporation assay was performed in absence and in presence of an exogenous metabolic
activation system (S9). Five Salmonella typhimurium tester strains (TA1535, TA97,
TA98, TA100, and TA102) were employed. The activity of the S9-mix and the
responsiveness of the tester strains were verified by including appropriate controls into
each experiment. The mutant frequencies of the controls were in the range of our
historical control values and the data published in the literature.
CAT-Acid Chloride was dissolved in DMSO. Based on toxicity observed in the range finder
assay concentrations between 31.6 and 3160 µg/plate were selected for the main
experiment. - GLP compliance:

The test item did not induce any dose related increase in the number of revertant colonies
in four of the five tester strains. However, strain TA98 showed a weak, dose related
increase of the of the colony numbers in absence of S9. The weak increase was confirmed
in a repeat assay conducted with this strain.
