Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 2000 · Certificado de Análisis (CoA) con cada lote
2',7'-Dichlorodihydrofluorescein diacetate (DCFH-DA) is a non-fluorescent cell-permeable compound widely used as a probe to detect reactive oxygen species (ROS) and oxidative stress in biological research. It is hydrolyzed by esterases to form DCFH, which is then oxidized to the highly fluorescent 2',7'-dichlorofluorescein (DCF) in the presence of ROS. This chemical has a CAS number of 4091-99-0, a molecular formula of C24H16Cl2O7, and a molecular weight of 487.29 g/mol. It should be stored at -15 to -20°C. The signal word for this product is "Warning." Molekula supplies 2',7'-Dichlorodihydrofluorescein diacetate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
