Abcam, ab275920, 2',7'-Dichlorofluorescein di-β-D-galactopyranoside (DCFDG)

Size: 25mg
MW 725.48 g/mol, Purity >98%. Highly sensitive fluorescent substrate for measuring galactosidase and galactocerebrosidase activity. Since the pKa of the released fluorophore is significantly lower than comparable fluorophores, it can retain appreciably more fluorescence in the highly acidic environment of the lysosome than other similar fluorophores. Absorption prior to enzyme hydrolysis is 290 nm.
