Modeling the Ames test

Mutation Research/Environmental Mutagenesis and Related Subjects, 1981
Despite the value and widespread use of the Ames test, little attention has been focused on standardizing quantitative methods of analyzing these data. In this paper, a realistic and statistically tractable model is developed for the evaluation of Ames-type data.

Mutagenicity of Glutathione and Cysteine in the Ames Test

Science, 1983
Postmitochondrial supernatant from rat liver and kidney homogenates transformed cysteine into a mutagen that reverted bacteria of the strain Salmonella typhimurium TA100 to histidine independence. Glutathione was also activated by kidney postmitochondrial supernatant but not by liver preparations.

Use of the Ames test in toxicology

Regulatory Toxicology and Pharmacology, 1985
The Salmonella/microsome assay (Ames test) is one of the most widely used short-term tests. Despite the ubiquitous presence of this assay and the large number of chemicals tested, there is still controversy over the value of Salmonella/microsome assay results in risk assessment.

The Salmonella (Ames) Test for Mutagenicity

Current Protocols in Toxicology, 1999
AbstractThe Ames test is a widely accepted short‐term assay for detecting chemicals that induce mutations in the DNA of organisms. The assay is a reverse mutation assay that detects the mutational reversion of his‐dependent Salmonella to his‐independent colonies.

Mutagenicity of white grape juice in the ames test

Food and Chemical Toxicology, 1996
The mutagenicity of commercially available white grape juice was evaluated in the Ames mutagenicity test. Grape juice elicited a positive mutagenic, response in Salmonella typhimurium strain TA104 and a weaker response in strains TA97, TA98, TA100 and TA1530.

The mutagenicity of some edible mushrooms in the Ames test

Food and Cosmetics Toxicology, 1982
The mutagenic activity of five wild and two cultivated species of edible mushrooms was studied in the Ames Salmonella/microsome test system. The wild mushrooms tested were four species of the genus Lactarius (L. necator, L. torminosus, L. helvus and L. rufus) and bolete (Boletus edulis).

Bacterial Reverse Mutation Test: Ames Test

Mutations can take many different forms, such as chromosomal rearrangements, variations in the number of chromosomes, and gene (point) mutations. These changes can be found in both mammalian and bacterial cells, frequently by microscopic examination or growth needs. To ensure safety, it is crucial to evaluate a chemical's mutagenic potential.
