Bacterial test systems have been used extensively to identify the mutagenic potential of new compounds. In particular, the Ames test has gained worldwide acceptance and is required by many regulatory agencies to support product registration. The grad

The mouse lymphoma assay (MLA) and Chinese hamster ovary (CHO) cell assay are sensitive indicators of mutagenicity. The CHO assay has been modified technically to permit treatment in suspension and soft agar cloning comparable to the MLA. This method

The hair-dye ingredients, HC Blue No. 1 (HCB1) and HC Blue No. 2 (HCB2), were tested for the induction of bacterial mutation using Salmonella typhimurium strains TA1535, TA1537, TA98 and TA100; and Escherichia coli strains WP2uvrA-. In addition, both

The L5178YTK+/- mouse lymphoma assay (MLA) has been utilized in several laboratories as a short-term test for chemical-induced forward mutation in cultured mammalian cells. In order to evaluate several technical modifications to the MLA, 42 chemicals

L5178Y/TK+/- cells were treated with 3-methylcholanthrene (3MC) in order to obtain thymidine-kinase-deficient mutants (TK-/-) which were resistant to trifluorothymidine (TFTr). Clones of TK-/- cells were harvested from soft agar and adapted to growth

Ochratoxin A (OA), a nephrotoxic mycotoxin, was evaluated for genotoxic potential in a battery of in vitro and in vivo assays. OA was not mutagenic to Salmonella typhimurium, either with or without metabolic activation, in the plate incorporation (Am
