Properties: Mol Formula: C32H32O15, Mol Weight: 656.6
IUPAC Name: 3′,6′-bis[[(2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy]spiro[2-benzofuran-3,9′-xanthene]-1-one
Synonym: Fluorescein di(|A-D-galactopyranoside), Spiro[isobenzofuran-1(3H),9′-[9H]xanthen]-3-one, 3′,6′-bis(beta-D-galactopyranosyloxy)-, 3′,6′-bis[[(2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy]spiro[2-benzofuran-3,9′-xanthene]-1-one
Fluorescein di-?-galactopyranoside is a fluorogenic substrate for ?-galactosidase. Upon enzymatic cleavage by ?-galactosidase, fluorescein is released and its fluorescence can be used to quantify ?-galactosidase activity. Fluorescein displays excitation/emission maxima of 490/514 nm , respectively.
