β-Galactosidase from Aspergillus oryzae

Catalog Number: (ALG493781-1G)

Supplier: ALADDIN SCIENTIFIC

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.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 hydrolysisProduct characteristics:1. Temperature range: effective temperature range: 20 ℃ - 70 ℃Optimum temperature: 40-60 ℃2. PH range: effective PH range: 2.0-7.5Optimum PH range: 4.0-5.5Enzymology Committee No.: 3.2.1.23Principle: 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.

H-Gly-Pro-Arg-Pro-OH Acetate Salt

Supplier: ALADDIN SCIENTIFIC

Description: H-Gly-Pro-Arg-Pro-OH Acetate Salt can bind to the polymerization site (D domain) in fibrinogen (K|i|= 400 mM) and prevent fibrinogen aggregation and fibrin polymerization. It also acts as an anticoagulant. Research shows that there is additional proteolysis of α, β and γ fibrinogen polypeptides during the cleavage of fibrinogen, which may also include the initial removal of fibrinopeptides.

Antipain, Dihydrochloride

Supplier: ALADDIN SCIENTIFIC

Description: Antipain, Dihydrochloride is a reversible protease inhibitor produced by actinomycetes. Antipain inhibits cathepsin A, B, and D as well as papain, trypsin and trypsin-like serine proteases. Antipain acts by forming a hemiacetal adduct between the aldehyde group of the inhibitor and the active proteinase. Effective at concentrations range from 1 to 100 μM.
