    Overview of Glycobiology

    Learn about the core sequences and common modifications of N-linked and O-linked glycans in this video. Analysis of these glycans can be accomplished with the use of deglycosylation enzymes, which can provide complete sugar removal with no protein degradation.

Peptide-N-Glycosidase F, also known as PNGase F, is an amidase that cleaves
between the innermost GlcNAc and asparagine residues of high mannose, hybrid, and complex oligosaccharides from N-linked glycoproteins (1).

PNGase F is the most effective enzymatic method for removing almost all N-linked oligosaccharides from glycoproteins. PNGase F digestion deaminates the asparagine residue to aspartic acid, and leaves the oligosaccharide intact for further analysis.

The growing importance of protein glycosylation in both pharmaceutical and clinical science, as well as basic research, is placing new demands on the quality of reagents for glycan analysis. NEB offers a selection of PNGase F reagents, all highly pure, to support a variety of applications.
