Genetic toxicology
Genotoxicological studies predict the genotoxicity of drugs and chemicals, including mutagenicity, destructiveness, and DNA damage. We can offer our customers the full range of tests in the ICH S2(R1) standard portfolio and comply with international GLP management specifications. The protocol was designed to meet the requirements of the US FDA, US EPA, ICH, OECD and CFDA guidelines. A rich historical database accumulated over the years, a stable technical team and professional senior researchers ensure that we are able to provide high-quality services to our customers in a timely and efficient manner. We are committed to developing cutting-edge genotoxicity methodology research, applying automated systems such as flow cytometry to genotoxicology, and participating in the joint validation of new technologies and methods of genotoxicity both domestically and internationally. In addition to the ICH standard test portfolio, we can also provide our customers with genotoxic mechanisms and additional test methods, as well as genotoxic evaluation of impurities that meet the requirements of ICH M7.
