Product Introduction

α1-3,4 Fucosidase is a broad specificity exoglycosidase that catalyzes the hydrolysis of terminal, non-reducing α1-3 and α1-4 linked fucose residues from oligosaccharides and glycoproteins.

• Recombinant enzyme with no detectable endoglycosidase or other exoglycosidase 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

Tech Tips

  • Repeated freeze/thaw cycles may reduce activity. Recommended storage temperature is 4°C.
  • Using 1-2 µl is a good starting point for a 1 hr incubation of 1µg of glycoprotein or 100 nM of oligosaccharide. 
  • Higher enzyme concentrations and longer incubation times may be required for the removal of α1-3 and α1-4 fucose residues from complex N-glycans. 
  • α1-3,4 Fucosidase can cleave the α1-3 fucose on the outer arm of N-linked glycans but is unable to remove the core α1-3 fucose residue. 
  • The storage buffer does not contain rHSA; however, we recommend supplementing the reaction with rHSA for optimal enzyme activity.
