AMES Test Service - Plate Incorporation Assay, OECD471的详细介绍 Art. No.: SSA-O471 Unit Service Analytics 1 - X Compounds Description In line with OECD 471 guideline, the Ames Mutagenicity Test is run on 5 different S.typhimurium strains - TA100, TA98, TA1535, TA1537, TA102 or on ...
So, we reiterate the importance of updating guideline No. 471 of the OECD to address the analysis of mixtures and the scientific evidence derived from the Ames Test in recent years. Finally, the study of the genotoxicity of medicinal plants is extremely important, since they are widely used ...

In addition, all of the Ames data used in this study was collected under the same test guideline, so the reported predictive power is only directly applicable within this guideline. Caution should be exercised when making predictions for datasets conducted outside of this such as under OECD TG...

Aim of this study was to compare two bacterial mutagenicity screening assays for their predictivity with respect to natural compounds for the OECD 471 guideline assay of bacterial reverse mutation. The micro-Ames uses 5 strains of S. typhimurium (TA98, TA100, TA102, TA1535 and TA1537) which...
has been used for over 15 years at several major pharmaceutical companies for screening the genotoxic potential of early drug candidates maximising hazard identification with minimizing resource expenditure. The Assay is run with two or five tester strains, in compliance with OECD Guideline 471, ICH ...
The current OECD TG471 Test Guideline provides minimal guidance for distinguishing positive from negative responses: “There are several criteria for determining a positive result, such as a concentration-related increase over the range tested and/or a reproducible increase at one or more concentrations...
