beta-N-Acetylhexosaminidase

Beta-N-Acetylhexosaminidase 是一種重組的 β-N-乙醯基己糖胺酶，選殖自肺炎鏈球菌 (Streptococcus pneumoniae)，並在大腸桿菌 (Escherichia coli) 中表現，其 N 端帶有 8xHis 標籤。它能催化水解寡糖與醣蛋白受質上的 non-reducing terminal N-Acetylglucosamine (GlcNAc) and N-Acetylgalactosamine (GalNAc)。

Package: 500 U

Official Name: beta-N-Acetylhexosaminidase
Description: This product is recombinant β-N-Acetylhexosaminidase (glycosyl hydrolase family GH20; E.C. 3.2.1.52), cloned from Streptococcus pneumoniae and expressed in Escherichia coli with an N-terminal 8xHis tag. It catalyzes the hydrolysis of the non-reducing terminal N-Acetylglucosamine (GlcNAc) and N-Acetylgalactosamine (GalNAc) from oligosaccharides and glycoprotein substrates.
Tag: 8x His Tag
Content: Purified lyophilized powder
Reconstitution: Dissolve the lyophilized product in 100 μL of molecular grade water to make a 5,000 units/mL solution in the Buffer.
Buffer: 50 mM Tris, 100 mM NaCl, pH 7.5
Storage: -20 °C as powder. Once reconstituted, 4 °C for five days or -20 °C for up to six months. Avoid freeze-thaw cycles.
Unit Definition: One unit is defined as the amount of enzyme required to catalyze the release of 1 nmole p-nitrophenol (pNP) from p-nitrophenyl-N-acetyl-β-D-glucosaminide (pNP-GlcNAc) in 1 min at 37°C in 100 μL. 1X Reaction Buffer 4 (50 mM Tris-HCl, 100 mM NaCl, pH 7.5).
