PNGase F (Glycerol-free)
NEBU cloned at NEB 37 75 Heat

Product Introduction

PNGase F is the most effective enzymatic method for removing almost all N-linked oligosaccharides from
glycoproteins. PNGase F (Glycerol-free) is an amidase, which cleaves between the innermost GlcNAc and asparagine residues of high mannose, hybrid, and complex oligosaccharides.

  • Glycerol-free for optimal performance in HPLC and mass spectrometry analysis
  • ≥ 95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Non-recombinant with no detectable endoglycosidase F1, F2 or F3 contamination
  • Optimal activity and stability for up to 24 months
  • Can be used under native or denaturing conditions
  • Optimized for deglycosylation of glycoproteins; leaves N-glycan core oligosaccharides intact and suitable for further analysis

Product Information

Description

Peptide: N-Glycosidase F, also known as PNGase F, is an amidase which is supplied glycerol free for optimal performance in HPLC intensive methods. PNGase F cleaves between the innermost GlcNAc and asparagine residues of high mannose, hybrid and complex oligosaccharides from N-linked glycoproteins (1).

Detailed Specificity
PNGase F is not able to cleave N-linked glycans from glycoproteins when the innermost GlcNAc residue is linked to an α1-3 Fucose residue (2). This modification is most commonly found in plant and some insect glycoproteins.

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to remove > 95% of the carbohydrate from 10 µg of denatured RNase B in 1 hour at 37°C in a total reaction volume of 10 µl.

Unit Definition Assay:
10 µg of RNase B are denatured with 1X Glycoprotein Denaturing Buffer (0.5% SDS, 40 mM DTT) at 100°C for 10 minutes. After the addition of NP-40 and GlycoBuffer 2, two-fold dilutions of PNGase F are added and the reaction mix is incubated for 1 hour at 37°C. Separation of reaction products are visualized by SDS-PAGE.

Application Features

  • Removal of N-linked glycans from glycoproteins
  • Preferred formulation for HPLC and MS intensive methods of glycoprotein analysis

Product Notes

  1. Since PNGase F activity is inhibited by SDS, it is essential to have NP-40 present in the reaction mixture. Why this non-ionic detergent counteracts the SDS inhibition is unknown at present.
  2. To deglycosylate a native glycoprotein, longer incubation time as well as more enzyme may be required. 
  3. PNGase F will not cleave N-linked glycans containing core α1-3 Fucose. 
  4. Repeated freeze thaw cycles degrade enzyme activity over time. 
  5. Typical reaction conditions: Please see Protocol tab

FAQs

  1. Is PNGase F compatible with downstream analysis such as HPLC and Mass Spectrometry?
  2. Why is my immunoprecipitated (IP) protein degraded? When I denature and add SDS all I see on my SDS-PAGE is a smear or no protein?
  3. Do detergents inhibit exoglycosidases/endoglycosidases?
  4. Does PNGase F work in Urea?
  5. How do I inhibit PNGase F?
  6. How much PNGase F should I use to remove my carbohydrate under native conditions?
  7. What is the difference between PNGase F, Endo H and O-Glycosidase?
  8. I tried the PNGase F on my glycoprotein and didn't see removal of the carbohydrate. What could be the problem?
  9. Why have the NEB Glycosidase enzymes changed reaction buffers? What are the new reaction buffers and can I still use an enzyme with its old buffer? Where can I find the composition of the old buffers?
  10. What are Glycosidases and their uses?
  11. What is a good endoglycosidase substrate?

Tech Tips

Don’t freeze-thaw this enzyme.  
You can use this enzyme under native or denaturing conditions.  
Under native conditions we recommend adding more enzyme and using longer incubation times.
PNGase F activity is inhibited by SDS, therefore under denaturing conditions it is essential to have NP-40 present in the reaction mixture in a 1:1 ratio.
PNGase F will not cleave N-linked glycans containing core α1-3 Fucose (PNGase A must be used in this instance).
