CUG (3-Carboxyumbelliferyl-β-D-galactopyranoside)(CAT: I013027) is a sensitive fluorogenic substrate commonly used to detect β-galactosidase enzyme activity. Upon enzymatic cleavage by β-galactosidase, CUG releases 3-carboxyumbelliferone, a highly fluorescent product that emits measurable fluorescence, enabling real-time monitoring of enzyme kinetics. This substrate is widely applied in biochemical assays, cell biology, and microbiology for studying gene expression, especially in systems where β-galactosidase serves as a reporter gene. Its high sensitivity and specificity make CUG a valuable tool in the Biochemical Reagents field for applications in enzyme activity analysis, drug screening, and diagnostic assay development.
