α1-3,4,6 Galactosidase is a broad specificity exoglycosidase that catalyzes the hydrolysis of terminal, non-reducing α1-3, α1-4 and α1-6-linked galactose residues from oligosaccharides.

  • 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 12 months
 
Product Source

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to cleave > 95% of the terminal, α-D-galactose from 1 nmol Galα1-3Galβ1-4Gal- 7-amino-4-methyl-coumarin (AMC), in 1 hour at 37°C in a total reaction volume of 10 μl.

Unit Assay Conditions

Two fold dilutions of α1-3,4,6 Galactosidase are incubated with 1 nmol AMC labeled substrate in 1X GlycoBuffer 1 and 1X rHSA 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 (1).

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.
    • A good positive control for α1-3,4 6 Galactosidase is p-Nitrophenyl α-D-galactopyranoside
    • The storage buffer does not contain rHSA; however, we recommend supplementing the reaction with rHSA for optimal enzyme activity
