On the limits of miniaturization of the Ames test

Limited availability of test compounds necessitates to miniaturize early pre-clinical toxicity or mutagenicity assays such as the Ames test. We discuss the factors that may be limiting for miniaturized assays such as the liquid microplate versions Ames MPF/Ames II. Upon reducing the number of bacteria a point will be reached where the solvent controls approach zero and thus would no longer allow to calculate a reliable "fold induction". It is concluded that the Ames II / Ames MPF liquid microplate versions of the Ames test achieve an optimal level of miniaturization without compromising reproducibility and sensitivity, particularly towards weak mutagens.

Weak mutagens in the Ames II / Ames MPF assay

Reducing the number of bacteria and amount of test compound in an assay like the Ames MPF should not compromise the sensitivity of the assay, and weak mutagens should still be detectable.

We have compared three typical "weak" mutagens in the Ames plate incorporation assay (from the NTP database) and in the Ames liquid microplate format. The detailed results can be seen on our homepage
