Reagent for fluorimetric assay of thiols.
Highly reactive fluorogenic reagent for the labeling of thiols for HPLC. ABD-F is nonfluorescent until reacted with thiols and therefore can be used to quantitate thiols in solution, as well as thiols separated by HPLC or TLC.
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)
4-Fluoro-7-sulfamoylbenzofurazan is a fluorescent reagent, which directly links to the sulfur atom of thiols without a flexible alkyl chain. It is used to detect low molecular thiols using high performance liquid chromatography.
