Application

The GlycoProfile™ Enzymatic In-gel N-Deglycosylation Kit is optimized to provide a convenient, reproducible method to N-deglycosylate and digest protein samples from one dimensional (1D) and two dimensional (2D) polyacrylamide gel pieces for subsequent mass spectrometry or HPLC analysis.
This procedure is suitable for Coomassie® Brilliant Blue and colloidal Coomassie stained gels. Silver stained gels may also be used if properly destained.

Principle

The kit includes Proteomics Grade PNGase F and trypsin enzymes necessary for N-linked deglycosylation and tryptic digestion, respectively. The samples can then be desalted and concentrated for analysis by MALDI-TOF MS or electrospray MS with subsequent database searching.

Quantity

Each kit contains reagents sufficient to deglycosylate and digest up to 10 samples.

Glycoprotein Deglycosylation

Information about Glycoprotein deglycosylation. The diversity of oligosaccharide structures, both O-linked and N-linked, often results in heterogeneity in the mass and charge of glycoproteins.

O-Linked Glycan Strategies

There is no enzyme comparable to PNGase F for removing intact O-linked sugars. Monosaccharides must be sequentially hydrolyzed by a series of exoglycosidases until only the Gal-b(1-3)-GalNAc core remains. O-Glycosidase can then remove the core structure intact with no modification of the serine or threonine residue.
