Xenometrix expands its genetic toxicology portfolio with a new, high-quality PB/NF-induced hamster S9 fraction preparation, complemented by dedicated service analysis for laboratories seeking a reliable testing partner.
Detecting genotoxic impurities in pharmaceuticals, packaging materials, and other consumer and industrial products is essential for protecting public health, and depends on robust and reliable safety assessment methods. International concerns about nitrosamines have driven collaborative efforts to strengthen testing strategies for these compounds. When evaluating the mutagenic potential of a nitrosamine through in vitro testing, regulatory authorities recommend the Enhanced Ames Test (EAT), which includes testing with 30% hamster S9 for metabolic activation.
To support this application, the new high-quality PB/NF-induced hamster S9 fraction preparation by Xenometrix is characterized by a high CYP conversion rate — key to the metabolic activation required for reliable nitrosamine detection. It is supplied as a frozen preparation in 1 mL or 5 mL formats, each accompanied by a comprehensive Certificate of Analysis. To ensure consistent performance, every batch is quality controlled across multiple Ames test formats, including the Petri dish assay, the liquid microplate fluctuation test, and the 6-well agar plate test.
Customers can profit from special price offers on this preparation until 30.06.2026.
Xenometrix also offers service analysis for customers who prefer to have their genetic toxicology testing carried out in-house at Xenometrix.
