  Removal of Core 1 and Core 3 O-linked disaccharide glycans from glycoproteins
- Properties & Usage
  
  Unit Definition
  One unit is defined as the amount of enzyme required to remove 0.68 nmol of O-linked disaccharide from 5 mg of neuraminidase digested, non-denatured fetuin (2) in 1 hour at 37°C in a total reaction volume of 100 µl (1 unit of both O-Glycosidase and PNGase F will remove equivalent molar amounts of O-linked disaccharides and N-linked oligosaccharides, respectively).
  
  Non-Denaturing Unit Definition Assay
  Two fold serial dilutions of O-Glycosidase are added to a reaction mixture of 5 mg of neuraminidase digested fetuin with 1X GlycoBuffer 2. The reaction mix is then incubated at 37°C for 1 hour. O-linked disaccharide carbohydrates are determined by the Morgan and Elson Assay (2).

- Product Notes
  Since O-Glycosidase is inhibited by SDS, it is essential to have NP-40 in the reaction mixture. It is not known why this non-ionic detergent counteracts the SDS inhibition at the present time. Double digest with Endo H must have NP-40 present (NP-40 does not inhibit Endo H).
  
  To deglycosylate a native glycoprotein, longer incubation time as well as more enzyme may be required.
  
  It is necessary to treat glycoproteins concomitantly with Neuraminidase and O-Glycosidase. Neuraminic Acid residues must be removed in order to allow O-Glycosidase to cleave the O-linked disaccharides. A general Neuraminidase (#P0720) or the O-Glycosidase and Neuraminidase bundle (#E0540S) is recommended.
  
  Under denaturing conditions the enzyme activity is increased two-fold. This observation is substrate dependent.

- Tech Tips
  
  Don’t forget to include Neuraminidase (P0720) in your reaction! It is necessary to treat glycoproteins concomitantly with Neuraminidase and O-Glycosidase. Neuraminic Acid residues must be removed in order to allow O-Glycosidase to cleave the O-linked disaccharides.
  
  NEB’s O-Glycosidase is the only available O-Glycosidase that catalyzes the removal of Core 1 and Core 3 O-linked disaccharides from glycoproteins
  
  You can use this enzyme under native or denaturing conditions
  
  Under native conditions we recommend adding more enzyme and using longer incubation times
  
  Under denaturing conditions the enzyme activity is increased two-fold. However, this observation may be substrate dependent.
