1. To deglycosylate a native glycoprotein, longer incubation time as well as more enzyme may be required.
2. Since PNGase F, Recombinant activity 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.
3. PNGase F, Recombinant will not cleave N-linked glycans containing core α1-3 Fucose.

1. Is there a difference between PNGase F (P0704/P0705) and PNGase F, Recombinant (P0708/P0709)?
2. I tried deglycosylating my glycoprotein with Remove-iT® PNGase F but did not see removal of the carbohydrate. What could be the problem?
3. What happens to the asparagine after PNGase removes the sugar?
4. Why is protein degraded? When I denature and add SDS all I see on my SDS-PAGE is a smear or no protein. Can a protease inhibitor cocktail be used in a PNGase F, Recombinant reaction?
5. What is the difference between PNGase F, Endo H and O-Glycosidase?
6. Does PNGase F work in Urea?
7. What are the typical reaction conditions for PNGase F, Recombinant?
8. How much PNGase F, Recombinant should I use to remove my carbohydrate under native or DTT denaturing conditions?
9. How do I inhibit PNGase F, Recombinant?
10. Is PNGase F, Recombinant compatible with downstream analysis such as HPLC and Mass Spectrometry?
11. What are Glycosidases and their uses?
12. Do detergents inhibit exoglycosidases/endoglycosidases?
13. 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?
14. What is a good endoglycosidase substrate?
