GB/T 21768-2008
AbolishedChemical - Test method of DNA damage and repair/unscheduled DNA synthesis with mammalian cells in vitro
化学品 体外哺乳动物细胞DNA损伤与修复/非程序性DNA合成试验方法
Application Summary AI generated
This standard specifies a laboratory test method for detecting DNA damage and repair in mammalian cells exposed to chemicals, specifically measuring unscheduled DNA synthesis (UDS) as an indicator of genotoxicity. It is applied in the safety assessment of industrial chemicals, pharmaceuticals, and consumer products to evaluate potential carcinogenic or mutagenic risks. The method is used by toxicology laboratories and regulatory agencies for in vitro genotoxicity screening prior to human or environmental exposure.
