Genetic and Alternative Toxicity Testing for Compound Screening, Derisking and Selection

Aragen has almost three decades of experience testing a wide variety of molecules including pharmaceuticals, agrochemicals and industrial chemicals.
Genotoxicity and mutagenicity both involve damage to genetic material. Genotoxicity refers to the capacity for a substance to damage genetic information within cells. Mutagenicity refers to the capacity for a substance to cause permanent, transmissible changes to genetic structure or amount of genetic material.
Testing at Aragen will identify genotoxicity as well as mutagenicity potential of your test article. We will provide reliable, efficient data as you screen libraries of multiple compounds for derisking your portfolio and candidate selection. Additionally we will also support your OECD safety and toxicology testing as you move towards regulatory filing.
Our toxicology and safety testing protocols are designed by technical experts in their respective fields and validated by regulatory bodies. It is important to note that study design will vary based on the type of molecule, its intended application and regulatory requirements. It is crucial to consult with toxicology and regulatory experts to create an appropriately tailored testing strategy.
