- Enzyme Specific Activity : ≥10 units/mg
- Volume : 40 µL
- Application : Glycoprotein deglycosylation
- pH Range : 7.5-9.5
- Enzyme Specificity
- Cleaves all N-linked complex, hybrid or high mannose oligosaccharides, unless α(1-3) core fucosylated, as in plant glycans and some insect glycans.
- Asparagine must be peptide bonded at both termini.
- Phosphate, sulfate and sialic acid groups attached to the oligosaccharide do not affect cleavage.
- This product is Endo F free.
- Enzyme Applications
- Release of intact N-linked glycans from glycopeptides and glycoproteins.
- Structure-function studies of N-glycosylated glycoproteins.
- Preparation of deglycosylated proteins for molecular weight estimation or crystallography studies
