Beta-Galactocidase Inhibitor Screening Kit, β-Gal converts β-Gal substrate to give an intensely fluorescent product (Ex/Em = 480/520 nm). In the presence of a β-Gal inhibitor, the reaction is impeded/abolished resulting in decrease or total loss of fluorescence. This assay kit can be used to screen/study/characterize the potential inhibitors of Beta Galactosidase. The assay is simple, high-throughput adaptable and can be performed within 30 min.
Introduction: Beta Galactosidase (β-Gal, EC: 18.104.22.168) is an enzyme which hydrolyzes the β-galactosides into monosacchanides. β-Gal is widely used as a reporter gene in the field of molecular biology. Senescence Associated β-Gal (SA-β-Gal) is an isoform of β-Gal which has the optimal activity at pH 6.0, and is mostly used as a biomarker for senescent cells (K802). β-Gal is an essential enzyme in humans and its deficiency results in Morquio"s Syndrome, a severe birth defect. β-Gal can also be used as a tool to study protein-protein interaction.
