  • 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
Bioz Badge Exists : True

Product Information

Description

α1-2,3,4,6 Fucosidase, cloned from bovine kidney, is a broad specificity exoglycosidase that catalyzes the hydrolysis of α1-2, α1-3, α1-4 and α1-6 linked fucose residues from oligosaccharides. α1-2,3,4,6 Fucosidase cleaves α1-2 and α1-6 fucose residues more efficiently than other linkages, and has slight activity towards α1-3 fucose residues.

Product Source

Cloned from bovine kidney and expressed in E. coli (1).

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to cleave > 95% of the α-L-fucose from 1 nmol of Fuc α1-2Galα1-4Glc- 7-amino-4-methyl-coumarin (AMC), in 1 hour at 37°C in a total reaction volume of 10 μl.

Unit Definition Assay
Two fold dilutions of α1-2,3,4,6 Fucosidase are incubated with 1 nmol AMC-labeled substrate in 1X GlycoBuffer 1 supplemented with 100 μg/ml BSA in a 10 μl reaction. The reaction mix is incubated at 37°C for 1 hour. Separation of reaction products are visualized via thin layer chromatography (2).

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.
  • Longer incubation times (4 hours to overnight) may be needed for complex, branched oligosaccharide substrates.
  • α1-2,3,4,6 Fucosidase will cleave branched α1-4 and α1-6 fucose residues but will not cleave branched α1-2 fucose residues.
  • α1-2,3,4,6 Fucosidase will partially cleave linear and branched α1-3 Fucose residues with low efficiency.
  • The storage buffer does not contain BSA; however, we recommend supplementing the reaction with BSA for optimal enzyme activity
