OxyBURST™ Green H₂DCFDA succinimidyl ester (2',7'-dichlorodihydrofluorescein diacetate, SE) is an amine-reactive assay reagent that can be used to prepare oxidation-sensitive conjugates of a wide variety of biomolecules and particles, including antibodies, antigens, peptides, proteins, dextrans, bacteria, yeast and polystyrene microspheres. Following conjugation to amines, the two acetates of OxyBURST™ Green H₂DCFDA can be removed by treatment with hydroxylamine at neutral pH to yield the dihydrofluorescein conjugate. OxyBURST™ Green H₂DCFDA conjugates are nonfluorescent until they are oxidized to the corresponding fluorescein derivatives.
