A bioassay of benzoin for possible carcinogenicity was conducted by incorporating the test chemical in diets of F344 rats and B6C3F1 mice. Benzoin is used as a photopolymerization catalyst, chemical intermediate, and flavor ingredient. Groups of 50 male rats were fed diets containing 125 or 250 ppm
The AS52/XPRT mutation assay was examined for sensitivity in the detection of chromosomal mutagens. 6 compounds identified as chromosomal mutagens in the mouse lymphoma assay (MLA) were tested for mutagenicity in AS52 cells using suspension treatment and soft agar cloning. The 6 compounds were
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 methodology eliminates the risk of metabolic cooperation
