Product Information

Description

N-Glycopeptide Binding Protein, also known as Fbs1-GYR lectin, is engineered to selectively bind and enrich a wide variety of N-glycopeptides in a complex proteomic sample to assist N-glycoprotein identification and discovery, without requiring the use of traditional lectin affinity chromatography (LAC) techniques, HILIC columns or cartridges. This engineered lectin, originating from human Fbs1 protein, exhibits improved specificity towards high mannose, complex, and hybrid N-glycans, as well as towards fucosylated and non-fucosylated, sialylated and non-sialylated, with bi-, tri- and tetra-antennary structures. N-Glycopeptide Binding Protein includes a SNAP-tag for immobilizing to create versatile workflows.

Unit Assay Conditions

Functional Testing (N-Glycan Enrichment) - A 200 μL reaction in 20 mM Tris-HCl, 50 mM NaCl, 0.2 mM TCEP, 10% acetonitrile, pH 8.0 containing 1 nmol of fluorescently labeled sialylglycopeptide and 100 μg N-Glycopeptide Binding Protein incubated for 30 minutes at 4°C results in ≥40% enrichment as determined by UV-Vis Spectroscopy at 520 nm.

Features

  • Engineered lectin, a glycan-binding protein that recognizes a wide variety of N-glycoforms, for enrichment and identification of glycopeptides and glycoproteins
  • Selectively binds and enriches N-glycopeptides in a complex proteomics sample, unlike other lectin affinity chromatography (LAC) techniques, HILIC, or other lectin-based enrichment methods
  • Significantly increased glycopeptide spectrum match and glycoprotein ID and discovery
  • Versatile workflow
