Hydrolysis of N- and Mucin-type O-glycans
OmniGLYZOR contains a mixture of immobilized enzymes for fast and efficient removal of N- and simple mucin-type O-glycans on antibodies, fusion proteins and other glycosylated proteins.
Removal of glycans is widely used to reduce heterogeneity to facilitate analysis of the protein by for example mass spectrometry. Deglycosylation can also be used to study the functional role of the glycans.
- Fast and efficient deglycosylation of N- and mucin-type O-linked glycans
- Ready-to-use spin column format - no enzymes interfering in the analysis
- Compatible with LC-MS

A mix of immobilized enzymes in spin columns for deglycosylation of glycoproteins carrying N- and simple O-glycansAbout OmniGLYZOR™
OmniGLYZOR contains enzymes required for the removal of N-glycans and the most commonly occurring mucin-type O-glycans, namely mono- and disialyl core 1 and Tn antigen (α-GalNAc).
The following activities are included in an OmniGLYZOR Microspin column:
- PNGase F
- O-glycosidase
- Sialidase
- α-GalNAcase
The glycoprotein sample is incubated with the OmniGLYZOR resin in a microspin column for 1-4 h under native reaction conditions. The deglycosylated glycoprotein is then easily collected by a centrifugation step.
OmniGLYZOR™ Kit
OmniGLYZOR is used for deglycosylation of glycoproteins carrying N- and simple O-glycans.
OmniGLYZOR Kit consists of:
- OmniGlyZOR Microspin columns
- PNGase F Lyophilized
- RapiGest™* SF surfactant
Certain N-glycosylation sites are poorly or not accessible to PNGase F unless the substrate protein is denatured. Remaining N-glycans after incubation on the OmniGLYZOR Microspin column can be removed by an additional deglycosylation step under denaturing conditions using the PNGase F Lyophilized and RapiGest™ SF surfactant included in the kit.
The enzymes hydrolyzing the O-glycans do not benefit from denaturation which is why the OmniGLYZOR columns should only be used under native conditions.
OmniGLYZOR Kit Microspin is provided in kits containing sufficient material to deglycosylate
5 × 50-100 µg or 10 × 50-100 µg glycoprotein.
- Fast and efficient one-pot deglycosylation of N- and O-linked glycans
- Compatible with LC-MS
- Complete removal of glycans for improved analysis of underlying protein
- Immobilized format increases enzyme-to-substrate ratio to enable fast deglycosylation

FAQ and Support
Popular FAQ
No, it is not recommended. We can only guarantee optimal performance for one-time use.
No, both N- and O-glycans are trimmed by the exoglycosidases present in OmniGLYZOR and do not longer represent the structures found on the intact glycoprotein substrate.
OmniGLYZOR hydrolyzes the amide bond between the polypeptide asparagine and the innermost GlcNAc of all mammalian asparagine-linked complex, hybrid, or high mannose oligosaccharides. It does not remove N-glycans with α1-3 core fucosylation.
