Deglycosylation in minutes for N-glycan analysis

Rapid PNGase F enables complete and rapid deglycosylation of antibodies and immunoglobulin fusion proteins, as well as other glycoproteins, in minutes. All N-glycans are released rapidly and without bias, and are ready to be prepared for downstream chromatography or mass spectrometry analysis. Rapid PNGase F creates an optimized workflow, reducing processing time without compromising sensitivity or reproducibility.

  • Complete deglycosylation of antibodies and immunoglobulin fusion proteins in 10 minutes
  • Recombinant enzyme; guaranteed endoglycosidase F1, F2 or F3 free
  • All reaction components are compatible with HPLC and mass spectrometry analysis
  • ≥ 95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability ensured for up to 12 months
  • Fast reaction setup

A growing number of antibodies and antibody fusions are currently used as therapeutic agents. A conserved N-glycan at Asn297 of the Fc region of IgG is critical for functional activity. Moreover, some antibodies have additional N-glycans that, together with the conserved site, affect recognition, half-life, and immune reactions.

Antibody glycosylation is heterogeneous, and variables in cell culture can increase glycan diversity. Monitoring glycosylation during production is essential to obtain the correct glycoprotein forms.

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 the oligosaccharide intact, keeping it suitable for further analysis.

Obtaining an accurate N-glycan profile in the shortest time possible is essential for effective process control. Typically, enzymatic release of antibody N-glycans using PNGase F requires an incubation time of several hours, followed by glycan derivatization and analysis by liquid chromatography and/ or mass spectrometry. In addition, incomplete deglycosylation can lead to biased results. Some glycans are easier to remove than others and unless deglycosylation is extensive, the profile obtained will not represent the correct composition of the therapeutic antibody.

Rapid PNGase F is an improved recombinant reagent that allows the complete and rapid deglycosylation of antibodies and fusion proteins in minutes. All N-glycans are released rapidly and without bias, and are ready to be prepared for downstream chromatography or mass spectrometry analysis. Rapid PNGase F creates an optimized workflow which reduces processing time without compromising sensitivity or reproducibility.

Application Features
Rapid PNGase F is an improved recombinant reagent that allows the complete and rapid deglycosylation of antibodies and fusion proteins in only minutes. All N-glycans are released rapidly and without bias, ready to be prepared for downstream chromatography or mass spectrometry analysis.

A variety of therapeutic monoclonal antibodies were used to validate Rapid PNGase F: different subclasses (IgG 1 to 4), isotypes (IgA, IgM, IgE), organisms (mouse, human, and humanized), sources (CHO, murine myeloma), and structures (IgG, IgG-fusions).

Rapid PNGase F can effectively remove all N-glycans from both conserved (i.e. Fc Asn297) and non-conserved (i.e. Fab N-glycans) glycosylation sites. Validation was in accordance with published data. Sensitivity and specificity are not compromised by a faster and more convenient glycoprotein characterization workflow using Rapid PNGase F.

Tech Tips
    • Before using the Rapid PNGase F, make sure all components are in solution.
    • Before incubation, make sure the Rapid Buffer, IgG, and rapid PNGase F are properly mixed.
    • If needed, reaction volumes can be scaled up or down, adjusting the amount of Rapid PNGase F accordingly. Altering the components ratio will lead to suboptimal results (for instance, using a larger reaction volume with only 1ul of enzyme).
    • For high throughput applications reactions can be prepared at room temperature. The deglycosylation reaction will begin once the temperature is raised to 50ºC.
    • Typically, the reaction is completed after 3-5 minutes at 50ºC. Incubation longer than 15 minutes will not result in further deglycosylation. If the reaction is still incomplete, try a 2 step protocol (pre-denaturation at 80C).
    • If inactivation of Rapid PGNase F is required after deglycosylation, heat for 20 minutes at 70C. Higher temperatures might result in coagulation of target antibody.
    • Avoid buffers containing SDS, as it inhibits PNGase F. Common stabilizing reagents such as Tween, Triton X-100, NP-40, octyl glucoside and non-detergent sulfobetaine, as well as traces of organic solvents, can prevent optimal rapid deglycosyl¬ation.
