beta-Galactosidase stain

REF : 94433-3X20UG
Marca : Sigma-Aldrich
Descrição detalhada : The gene of beta-galactosidase from E. coli is widely used as a reporter gene assay marker. Although X-gal is well known reagent to detect beta-galactosidase in cell or tissue samples, the assay using these reagents require to fix cells or tissues due to the poor cell-permeability. In addition, so far developed the assay using fluorescence reagents can not clearly differentiate beta-galactosidase-expressed cells or regions.To overcome these issues, Urano, Kamiya and co-workers have successfully developed a stain ideally possesses cell-permeability and the ability to retain in intracellular region.1)By the enzymatic reaction, the beta-Galactosidase stain immediately forms a quinone methide that acts as electrophile when proteins containing nucleophilic functional groups nearby the molecules. By the probe undergoes the reaction with a protein, the conjugates become fluorescent compounds. Thus, it allows a single-cell analysis because it does self-immobilizing to the intracellular proteins.Exciation Maximum: 530 nm (+/- 10 nm)Emission Maximum: 550 nm (+/- 10 nm)Reference: 1) Y.
