Product Information

• Name: 4-(Aminosulfonyl)-7-fluoro-2,1,3-benzoxadiazole
• Synonyms: 7-fluoro-2,1,3-benzoxadiazole-4-sulfonamide
• Brand: TRC
• Description: Applications A water soluble pH dependent bifunctional fluorogenic reagent for the sensitive and specific detection of protein thiols. ABD-F is highly reactive and specific for protein thiols, and its selectivity is superior to that of other sulfhydryl-reactive fluorophores such as fluorescein maleimide, 5-iodoacetamidofluorescein, 5-I-AEDANS, dansylaziridine, and bimane. Fluorescence: max Abs. l = 385nm, max Em. l = 520nm; Molar Abs. > 4.5x103 (ca. 315nm)References Hiratsuka., T.,: J. Biol. Chem., 268, 24742 (1993), Treuheit, M.J., et al.: Anal.
