The Tg.AC mouse is being evaluated for use in short-term carcinogenicity bioassays. Because the dermal test protocol necessitates dissolving test agents we determined the effects of several solvents on responsiveness of hemizygous mice to dermal applications of the classical skin tumor promoter. phorbol 12-myristate 13-acetate (TPA). Mice of both sexes received dermal applications of either ace...
