Product Overview
PNGase F is the most efficient enzymatic method to remove nearly all N-glycans from glycoproteins. PNGase F digests the glycosidic bond between the innermost N-acetylglucosamine and asparagine residues. It cleaves N-glycans attached to glycoproteins, including high-mannose, hybrid, and complex oligosaccharide glycoforms.
Key Features
Efficient N-glycan release enzyme
PNGase F-Fast enables enzymatic removal of N-linked glycans from glycoproteins by cleaving the bond between the innermost N-acetylglucosamine and asparagine residues. It is applicable to high-mannose, hybrid, and complex N-glycan structures.
Preservation of glycan core structure
After enzymatic digestion, released N-glycans retain their core structures, supporting downstream analytical applications.
Rapid reaction setup
Supports fast deglycosylation workflows with a typical setup time of approximately 10 minutes at 50 °C under recommended conditions.
High-concentration formulation
High-concentration design allows flexible adjustment of enzyme input in different sample types and reaction scales, supporting more demanding or high-load glycoprotein workflows.
High purity
Purity is typically ≥95% as determined by standard analytical methods.
Flexible reaction compatibility
Compatible with both denaturing and non-denaturing digestion conditions depending on experimental requirements.
Multiple product formats available
Different formats are available to support diverse application needs (e.g., HBP003006 / HBP003004 / HBP003005).
Applications
N-glycan release for analytical workflows
Used for enzymatic removal of N-linked glycans in workflows typically performed at 50 °C for downstream structural analysis.
CE and LC/LC-MS-based glycan analysis
Suitable for sample preparation in capillary electrophoresis (CE), HPLC, and LC-MS-based N-glycan profiling applications.
Glycoprotein modification for downstream applications
Applied in workflows requiring removal of N-glycans prior to protein modification or bioconjugation processes, including ADC-related research applications depending on experimental design.
