Resorufin β-D-galactopyranoside is a fluorogenic substrate for β-galactosidase. β-galactosidase is a commonly used reporter to monitor for gene expression in molecular biology. Resorufin β-D-galactopyranoside is essentially non-fluorescent until β-galactosidase enzymatic activity releases the fluorescent dye, resorufin. Unlike fluorescein-based substrates, resorufin β-D-galactopyranoside releases the orange-fluorescent resorufin after a single enzymatic hydrolysis event with fast enzyme kinetics, making this substrate useful for flow cytometry, ELISA, and high throughput screening applications. Resorufin β-D-galactopyranoside may be used to detect β-galactosidase enzymatic activity in live cells after permeabilization or may be used to detect β-galactosidase enzymatic activity in cellular extracts. Enzymatic activity is detected by fluorescence with an excitation near 571 nm and fluorescence emission near 585 nm. .
