PNGase F (Glycerol-free)
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

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.

Product Notes
- 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.
- To deglycosylate a native glycoprotein, longer incubation time as well as more enzyme may be required.
- PNGase F will not cleave N-linked glycans containing core α1-3 Fucose.
- Repeated freeze thaw cycles degrade enzyme activity over time.
- Typical reaction conditions: Please see Protocol tab

- 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?
- Do detergents inhibit exoglycosidases/endoglycosidases?
- Does PNGase F work in Urea?
- How do I inhibit PNGase F?
- How much PNGase F should I use to remove my carbohydrate under native conditions?
- What is the difference between PNGase F, Endo H and O-Glycosidase?
- I tried the PNGase F on my glycoprotein and didn't see removal of the carbohydrate. What could be the problem?
- 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?
- What are Glycosidases and their uses?
- What is a good endoglycosidase substrate?
Tech Tips
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).
