Product Description

Biochemical/physiological effects:

β- Galactosidase acts on the ends of disaccharides, glycoconjugates and polysaccharides β- D-galactosyl. It can be used to mediate sugar transfer reactions, such as galactooligosaccharide (GOS) synthesis. ββ- Galactosidase can be used in glycobiology and biotechnology.

β- Galactosidase cleaves lactose into monosaccharide components, glucose and galactose. It can also catalyze the transglycosylation of glucose to form isolactose, which acts as β- The inducer of galactosidase.

Product application:

β- Galactosidase (from Aspergillus oryzae) has been used for: ① in vitro nuclear magnetic resonance (NMR); ② As β- Galactosidase analysis standard, determination of cell related β- Galactosidase concentration;

③ To modify the sugar residues on the surface of the mutant synovial cells to study the adhesion; ④ Lactase hydrolysis experiment; ⑤ Reverse phase (RP) adsorption experiment; ⑥ Whey lactose hydrolysis

Product characteristics:

1. Temperature range: effective temperature range: 20 ℃ - 70 ℃

Optimum temperature: 40-60 ℃

2. PH range: effective PH range: 2.0-7.5

Optimum PH range: 4.0-5.5

Enzymology Committee No.: 3.2.1.23

Principle: lactase can decompose β- A galactoside bond that produces glucose and galactose.

Definition of enzyme activity: 1g lactase decomposes ONPG (o-nitrobenzene) every minute at PH 4.5 and 37 ℃ β- D-galactopyranoside) to produce 1umol ONP (o-nitrophenol), that is, one enzyme activity unit is expressed in u/g.
