GB/T 21769-2008
AbolishedChemical - In vitro 3T3 NRU phototoxicity test method
化学品 体外3T3中性红摄取光毒性试验方法
Application Summary AI generated
This standard specifies an in vitro method using a mouse fibroblast cell line (3T3) and neutral red uptake (NRU) to assess the phototoxic potential of chemicals. It is applied in the safety evaluation of pharmaceuticals, cosmetics, and industrial chemicals to determine if a substance becomes toxic upon exposure to ultraviolet or visible light. The test serves as an alternative to animal testing, primarily used in regulatory toxicology and product development within the healthcare and chemical industries.
