Ames test procedure. The Ames test is a widely employed method that uses bacteria to test whether a given chemical can cause mutations in the DNA of the test organism. More formally, it is a biological assay to assess the mutagenic potential of chemical compounds. [1]
Bruce Nathan Ames (December 16, 1928 – October 5, 2024) was an American biochemist who was a professor of biochemistry and Molecular Biology Emeritus at the University of California, Berkeley, and was a senior scientist at Children's Hospital Oakland Research Institute (CHORI). [2]
Genotoxicity is the property of chemical agents that damage the genetic information within a cell causing mutations, which may lead to cancer.While genotoxicity is often confused with mutagenicity, all mutagens are genotoxic, but some genotoxic substances are not mutagenic.

Overview of the use of the SOS response for genotoxicity testing. The SOS chromotest is a biological assay to assess the genotoxic potential of chemical compounds. The test is a colorimetric assay which measures the expression of genes induced by genotoxic agents in Escherichia coli, by means of a fusion with the structural gene for β-galactosidase.
A micronucleus test is a test used in toxicological screening for potential genotoxic compounds. The assay is now recognized as one of the most successful and reliable assays for genotoxic carcinogens , i.e., carcinogens that act by causing genetic damage and is recommended by the OECD guideline for the testing of chemicals.
