A new Salmonella tester strain (TA102) with A X T base pairs at the site of mutation detects oxidative mutagens.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1982
A new tester strain, TA102, is described as an addition to the set of strains for the Salmonella/microsome mutagenicity test. This strain contains A X T base pairs at the site of the mutation (determined by DNA sequence analysis) in contrast to the other
