重组IdeS蛋白酶来源于酿脓链球菌(Streptococcus pyogenes),可以特异性的识别IgG,并在IgG下铰链区的特定位点进行酶切,使IgG水解为完整的F(ab’)2片段和Fc片段。IdeS 蛋白酶可识别人源和其他多种动物来源的IgG,比如小鼠、兔、猴、绵羊以及人动物嵌合IgG等。本公司生产的IdeS蛋白酶采用大肠杆菌重组表达,具有严格的底物选择性和良好的酶切活性,是表征抗体或者Fc融合蛋白结构的有力工具。

Recombinant IdeS protease is derived from Streptococcus pyogenes. It specifically recognizes IgG and cleaves at a specific site in the lower hinge region of IgG, hydrolyzing IgG into intact F(ab’)₂ fragments and Fc fragments. IdeS protease can recognize human IgG and IgG from many other animal species, such as mouse, rabbit, monkey, sheep, and human-animal chimeric IgG. Our IdeS protease is recombinantly expressed in E. coli. It has strict substrate selectivity and excellent cleavage activity, serving as a powerful tool for structural characterization of antibodies or Fc fusion proteins.
