Typical Reaction Conditions for α-N-Acetylgalactosaminidase (P0734)

  1. Combine 1 μg of glycoprotein or 100 nmol of oligosaccharide and H2O (if necessary) to make an 8 μl total reaction volume.

  2. Add 1 μl of 10X GlycoBuffer 1 and 1 μl of rHSA (diluted 1:10 from 100X concentration) to make a 10 μl total reaction volume.

  3. Add 1 μl of α-N-Acetylgalactosaminidase.

  4. Incubate at 37°C for 1 hour.


    Notes
  • The amount of exoglycosidase enzyme required varies when different substrates are used. Start with 1-2 μl for 1 μg of glycoprotein or 100 nM of oligosachride for one hour in a 10-25 μl reaction. If there is still undigested material, let the reaction go overnight.
  • The reaction can be scaled up linearly
  • Several exo- and endo-glycosidases can be used together in one digest. For buffer recommendations, please referance the Glycobiology Double Digest Chart .
  • For a more detailed characterization of several glycosidase enzymes, please referance the Detailed Characterization of Several Glycosidase Enzymes page.
