    摘要: Disclosed herein is a novel forward mutation assay based on 5-fluorouracil (5-FU) resistance which utilizes a strain of Salmonella typhimurium derived from the Ames strain TA100. More specifically, the invention provides a high throughput alternative to the standard Ames mutation assay for the evaluation of the genotoxicity activity of compounds during an early stage of the drug development process. The invention also identifies the upp locus as a mutational target that is capable of detecting a diverse spectrum of mutagenic events and further describes a S. typhimurium tester strain, designated FU100 (his+, rfa, ΔuvrB, pkM101, 5-fluorouridine resistant) for use in the assay of the invention.
