title: Effect of the rat liver S9 fraction on the mutagenicity of azathioprine in the Salmonella/mammalian microsome assay.
abstract: Azathioprine is a direct acting mutagen in Salmonella typhimurium TA100 and TA1535. Addition of rat liver S9 fraction with or without co-factors, or glutathione, causes a decrease in the mutagenicity of azathioprine in TA100 and an increase in TA1535, indicating the effect of SH groups.
