Assessment of the performance of the Ames MPF™ assay: A multicenter collaborative study with six coded chemicals
The Ames MPF™ is a miniaturized, microplate fluctuation format of the Ames test. It is a standardized, commercially available product which can be used to assess mutagenicity in Salmonella and E. coli strains in 384-well plates using a color change-based readout. Several peer-reviewed comparisons of the Ames MPF™ to the Ames test in Petri dishes confirmed its suitability to evaluate the mutagenic potential of a variety of test items. An international multicenter study involving seven laboratories tested six coded chemicals with this assay using five bacterial strains, as recommended by the OECD test guideline 471. The data generated by the participating laboratories was in excellent agreement (93%), and the similarity of their dose response curves, as analyzed with sophisticated statistical approaches further confirmed the suitability of the Ames MPF™ assay as an alternative to the Ames test on agar plates, but with advantages with respect to significantly reduced amount of test substance and S9 requirements, speed, hands-on time and, potentially automation.
期刊介绍：
Mutation Research - Genetic Toxicology and Environmental Mutagenesis (MRGTEM) publishes papers advancing knowledge in the field of genetic toxicology. Papers are welcomed in the following areas:
New developments in genotoxicity testing of chemical agents (e.g. improvements in methodology of assay systems and interpretation of results).
Alternatives to and refinement of the use of animals in genotoxicity testing.
Nano-genotoxicology, the study of genotoxicity hazards and risks related to novel man-made nanomaterials.
Studies of epigenetic changes in relation to genotoxic effects.
The use of structure-activity relationships in predicting genotoxic effects.
The isolation and chemical characterization of novel environmental mutagens.
The measurement of genotoxic effects in human populations, when accompanied by quantitative measurements of environmental or occupational exposures.
The application of novel technologies for assessing the hazard and risks associated with genotoxic substances (e.g. OMICS or other high-throughput approaches to genotoxicity testing).
MRGTEM is now accepting submissions for a new section of the journal: Current Topics in Genotoxicity Testing, that will be dedicated to the discussion of current issues relating to design, interpretation and strategic use of genotoxicity tests. This section is envisaged to include discussions relating to the development of new international testing guidelines, but also to wider topics in the field. The evaluation of contrasting or opposing viewpoints is welcomed as long as the presentation is in accordance with the journal''s aims, scope, and policies.
