Catalog Number: (76482-300)

Supplier: AAT BIOQUEST INC

Description: Resorufin beta-D-galactopyranoside is a fluorogenic galactosidase substrate that generates a red fluorescent product upon interaction with the enzyme.

Catalog Number: (103011-314)

Supplier: Anaspec Inc

Description: Unlike FDG that requires a two-step hydrolysis to generate maximum fluorescence, resorufin β-D-galactopyranoside requires only a single-step hydrolysis reaction to attain full fluorescence. This substrate is especially useful for sensitive enzyme measurements in ELISAs. The relatively low pKa (~6.0) of resorufin (the enzymatic hydrolysis product of resorufin galactoside) with Ex/Em=573/585 nm permits continuous measurement of enzymatic activity. Resorufin galactoside has also been used to quantitate β-galactosidase activity in single yeast cells by flow cytometry and to detect immobilized β-galactosidase activity.
