产品描述（Product Details）
This product is an IgG-specific endoglycosidase hydrolyzing complex N-glycans at the Fc N-glycosylation sites. It is derived from Streptococcus pyogenes and expressed in E. coli. The enzyme contains a His-tag and the molecular weight is 110 kDa.The enzyme deglycosylates IgG after the core GlcNAc and display limited activity on high-mannose and hybrid-type glycans.
应用说明（Application）
Endo S2 is specific for N-glycans attached on the Fc-domain of IgGs, and hydrolyzes Fc-glycans of all human IgG subclasses and IgG from many other species, including mouse, rat, monkey, sheep, goat, cow, and horse.
单位定义（Unit Definition）
One unit deglycosylates ≥ 95% of 1 μg human IgG, when incubated in 10 mM sodium phosphate, 150 mM NaCl, pH7.4 at 37°C for 30 min.
酶活（Enzyme Activity）
>200 U/μL
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
制剂（Formulation）
Supplied as 0.2 μm filtered solution in PBS, pH7.4 with glycerol as protectant.
