Product Introduction

Deglycosylation in minutes for intact antibody analysis

Developed for proteomic applications, Rapid PNGase F (non-reducing format) enables complete and rapid deglycosylation, while preserving disulfide bonds. This facilitates high throughput proteomics applications and methods for antibody characterization by mass spectrometry, such as intact mass analysis. Rapid PNGase F (non-reducing format) combines the advantages of Rapid PNGase F (fast processing time), with non-reducing conditions, preserving quaternary structure.

Product Information

Description

PNGase F is the most effective enzymatic method for removing almost all N-linked oligosaccharides from glycoproteins. PNGase F digestion deaminates the aspargine residue to aspartic acid, and leaves both the protein and the oligosaccharide intact, keeping them suitable for further analysis (1).
Developed for proteomic applications, Rapid PNGase F (non-reducing format) is a reformulated version of Rapid PNGase F (NEB #P0710 ) that allows the complete and rapid deglycosylation of antibodies and fusion proteins in minutes, while preserving disulfide bonds. All N-glycans are released rapidly and without bias, facilitating high throughput proteomics applications and methods for antibody characterization by mass spectrometry such as intact mass analysis. Rapid PNGase F (non-reducing format) combines the advantages of Rapid PNGase F (fast processing time), with the non-reducing conditions preserving quaternary structure.

Specificity

Rapid PNGase F (non-reducing format) cleaves all complex, hybrid and high-mannose type glycans from antibodies and related proteins. Core α1,3 fucosylation (found in immunoglobulins expressed in plant or insect cells) is resistant to both Rapid PNGase F and PNGase F.

Application Features

Rapid PNGase F (non-reducing format) is effective on a variety of antibodies despite their structural diversity. Intact protein characterization using Rapid PNGase F (non-reducing format) is convenient, and complete (reducing biased results). The fast processing time decreases the risk of artifacts and unwanted protein modifications (oxidation, deamidation) that could be introduced by lengthy incubations with standard N-glycan removal protocols. Samples are ready to be prepared for downstream chromatography or mass spectrometry analysis, providing accurate and reproducible results.

For streamlined proteomic workflows, Rapid PNGase F (non-reducing format) is directly compatible with Trypsin-ultra™, Mass Spectrometry Grade (NEB #P8101 ). 

Product Notes

  1. Storage: It is recommended to store this kit at -20°C. All components will be stable for at least two years if stored correctly.
  2. The pre-incubation step at 75°C is strictly required. Deglycosylation takes place once the enzyme is added and incubated at 50°C.
  3. The target protein should be in a solution compatible with Rapid PNGase F (non-reducing format) activity. Avoid buffers containing SDS, as it inhibits PNGase F. Common stabilizing reagents such as Tween, TritonX-100, NP-40, octyl glucoside and non-detergent sulfobetaine, as well astraces of organic solvents, can prevent optimal rapid deglycosylation.
  4. Buffer exchange (by dialysis, spin columns, or microfiltration) is recommended to prepare samples for liquid chromatography/mass spectrometry.

Tech Tips

If needed, reaction volumes can be scaled up or down, adjusting the amount of enzyme accordingly. Altering the components ratio will lead to suboptimal results (for instance, using a larger reaction volume with only 1 µl of enzyme).
Reactions can be set up at room temperature.The pre-incubation step at 75°C is strictly required. The deglycosylation step takes place once Rapid PNGase F (non-reducing format) is added and incubated at 50°C.
Typically, the reaction is completed after 10 minutes at 50°C. Incubation longer than 15 minutes will not result in further deglycosylation.
If the reaction is not complete, try increasing the amount of Rapid PNGase F (non-reducing format) Buffer (up to 4 µl in a 10 µl total volume).
For complex substrates, reducing agents are sometimes strictly required. In those cases, complete deglycosylation under non-reducing conditions might not be feasible. Rapid PNGase F (NEB #P0710 ) can be used instead.

Specification Change Notifications

Effective May 12, 2025:

  • The shelf life of Rapid™ PNGase F is being extended from 12 months to 24 months.
  • The storage temperature of Rapid™ PNGase F and associated components is changing from 4°C to -20°C.
  • Two assays are being removed from the specification, Glycosidase Activity (Endo F2, F3) and Glycosidase Activity (Endo F1, F2, H) as Recombinant PNGase F enzymes are specifically engineered to be endoglycosidase F1-, F2-and F3-free, therefore these assays are not applicable.
