β-galactosidase

β-Galactosidase (GAL) is a glycoside hydrolase that hydrolyzes the β-glycosidic bond formed between galactose and its organic part, and naturally catalyzes the hydrolysis of the galactosidic bond in oligosaccharides and disaccharides for the degradation of lactose and the production of low-lactose and lactose-free lactose products that are beneficial to lactose intolerant patients.

D-Ribonolactone is a sugar lactone and an inhibitor of β-galactosidase in Escherichia coli (Ki: 26 mM).

α-Galactosidase is an endogenous glycosidase that can break down oligosaccharides and glycolipids containing α-galactoside bonds and can be used in the study of Fabry disease.

Maltotriose is an inducer of E. coli maltose regulator, the second most abundant sugar in brewing. It induces beta-galactosidase synthesis.

Maltotriose (Standard) is the standard substance of Maltotriose, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Maltotriose is an inducer of E. coli maltose regulator, the second most abundant sugar in brewing. It induces beta-galactosidase synthesis.

Galactostatin is an inhibitor of β-galactosidase.

NIR-BG2 is a near-infrared fluorescent probe that targets senescence-associated β-galactosidase (SA-β-Gal). Upon activation by SA-β-Gal, NIR-BG2 undergoes hydrolysis, releasing an electrophilic methylquinone that covalently binds to surrounding proteins for in situ labeling, enhancing the fluorescence signal 16-fold at 709 nm. NIR-BG2 holds potential for in vivo imaging studies of cellular senescence.

Gypenoside L is a saponin that can be found in Gynostemma pentaphyllum. Gypenoside L increases the SA-β-galactosidase activity, promotes the production of senescence-associated secretory cytokines. Gypenoside L also can activate p38 and ERK MAPK pathways and NF-κB pathway to induce senescence. Gypenoside L exhibits anti-tumor and anti-inflammatory activities.
