β-Galactosidase - Wikipedia
β-Galactosidase (EC 3.2.1.23, beta-gal or β-gal; systematic name β-D-galactoside galactohydrolase) is a glycoside hydrolase enzyme that catalyzes hydrolysis of terminal non-reducing β- D -galactose residues in β- D -galactosides. (This enzyme digests many β-Galactosides, not just lactose.
Senescence β-Galactosidase Staining Kit - Cell Signaling Technology
The Senescence β-Galactosidase Staining Kit is designed to conveniently provide reagents needed to detect β-galactosidase activity at pH 6, a known characteristic of senescent cells. Papers have published using this kit in both cells and frozen tissue.

In this test, you use a molecular decoy called ONPG (Ortho-nitrophenyl-b-D-galactopyranoside) that will turn to a yellow color in the presence of this enzyme. ONPG is an analog of lactose that the enzyme can break down to produce a yellow colored end-product, O-nitrophenol.
Beta-Galactosidase Activity Assay - UC Davis
2014年6月19日 · β-Galactosidase is able to hydrolyze (cleave) β-D-galactosides. This enzyme facilitates growth on carbon sources like lactose by cleaving it into a molecule of glucose and a molecule of galactose which the cells can catabolize and grow on.

2024年10月21日 · The ONPG assay is an enzyme activity assay used to measure the activity of the enzyme β-galactosidase (β-gal). The breakdown of ONPG by β-gal results in a color change that can be measured and equated to the activity of β-gal. Note. The ONPG assay is one of many enzyme activity assays. Enzyme activity assays can be used to measure the ...

Beta-galactosidase is a lysosomal enzyme responsible for catalyzing the hydrolysis of gangliosides. Isolated deficiency of this enzyme can be expressed clinically as 2 different diseases, GM1 gangliosidosis (GM1) and Morquio syndrome B (MPS IVB: mucopolysaccharidosis IVB), or in some patients as a disease that combines the skeletal features of ...
β-‐Galactosidase is encoded by the lacZ gene of the lac operon in E. coli. It is a large (120 kDa, 1024 amino acids (http://www.ecocyc.org/ECOLI/NEW-‐IMAGE?type=ENZYME& object=BETAGALACTOSID-‐CPLX) ) protein that forms a tetramer.
The Beta-Glo® Assay System provides a sensitive luminescent reagent for detecting and quantifying β-galactosidase activity in a homogeneous assay format. It is brighter and more sensitive than any other currently available luminescence-based β-galactosidase assay.
