qa-bio Endo F Multi-Kit说明书

Endo F Multi-Kit将在天然和变性条件下将N-连接的聚糖脱糖基化。每种酶对N-连接的聚糖释放具有不同的特异性。可以选择组合使用这三种酶以*去除糖蛋白或肽上存在的所有N-连接的聚糖,或者独立使用每种酶,从而确定存在的N-聚糖的类型。

KE-EFX3

产品描述

推荐使用Endo F Multi-kit对由于在蛋白质的三维结构中的聚糖位置而在非变性条件下对PNgase F裂解具有抗性的天然蛋白质进行去糖基化处理,因为已知这些酶对蛋白质构象的敏感性较低。

每一种酶的具有不同的N-连接的聚糖的特异性:
内切糖苷酶F1断裂这样的高甘露糖和某些杂合型N-聚糖
内切糖苷酶F2释放双触角和高甘露糖聚糖(以40X减小的速率)
内切糖苷酶F3将释放triantennarry和岩藻糖基双触角N-聚糖

应用:
–抗PNGase F切割的天然蛋白质的去糖基化–
聚糖类型的测定(高甘露糖,双触角,三/四臂触角)
–脱糖基化时通常会沉淀的脱糖基化蛋白
– X射线晶体学

这三种酶在寡糖的核心中的两个GlcNAc残基之间裂解天冬酰胺连接的(N-连接的)寡糖,生成截短的糖分子,其中一个N-乙酰氨基葡糖残基保留在天冬酰胺上,增强了蛋白质的溶解性。相反,PNGase F可以完整清除寡糖。

使用说明

1.向Eppendorf管中加入多达200μg糖蛋白。用去离子水将最终体积调整为34μl。
2.加入10μlEndo F2 / F3 5x反应缓冲液,250 mM乙酸钠pH 4.5。如果单独使用Endo F1酶,请使用Endo F1缓冲液,250 mM磷酸钠pH 5.5。
4.将2.0μl每种酶添加到反应中。在37°C下孵育3小时。
通过SDS-PAGE监控切割。

Endo D

Endo D is an endoglycosidase that cleaves within the chitobiose core of paucimannose N-linked glycans, with or without extensions in the antennae, from glycoproteins and glycopeptides.

  • Tagged with a chitin binding domain (CBD) for easy removal
  • Recombinant enzyme with no detectable exooglycosidase or other endoglycosidase contaminating activities
  • Glycerol -free for optimal performance in HPLC and mass spectrometry analysis
  • ≥95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability for up to 12 months

Endo F2

Endo F2 is a highly specific recombinant endoglycosidase which cleaves within the chitobiose core of asparagine-linked complex biantennary and high mannose oligosaccharides from glycoproteins and glycopeptides. Endo F2 cleaves biantennary glycans at a rate approximately 20 times greater than high mannose glycans.  The activity of Endo F2 is identical on biantennary structures with and without core fucosylation.  However, Endo F2 is not active on hybrid or tri- and tetra-antennary oligosaccharides.

  • Endo F2 is tagged with a chitin binding domain (CBD) for easy removal from a reaction
  • Recombinant enzyme with no detectable exooglycosidase or other endoglycosidase contaminating activities
  • Glycerol -free for optimal performance in HPLC and mass spectrometry analysis
  • ≥95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability for up to 24 months
