Figure Lengend Snippet: Comparison of metabolic activation systems in the PMR-W-treated TA1537 strain in the Ames test. The mean of the number of revertant colonies in the absence and presence of the 5% Aroclor1254-induced rat S9, 5% human liver S9, 5% and 10% CYP1A1 bactosome (instead of liver s9); combination of 5% human liver S9 and 5% CYP1A1 bactosome; and 10%, 20%, and 40% in vivo BaP-treated rat liver S9 are shown in ( A ). The BaP responses are shown in ( B ). 2AA 0.5 μg/plate (S9 positive control), 9AA 50 μg/plate (positive control), and BaP (Aroclor 1254-induced rat S9 positive control) were treated with positive control.
Article Snippet: Briefly, S. typhimurium strains TA98, TA100, TA1535, and TA1537 and E. coli WP2 uvrA (Molecular Toxicology Inc., USA) were used as the test strains in the presence or absence of 5% v/v Aroclor 1254-induced rat liver S9 metabolic system (S9 mix).
