Endo F1, Endoglycosidase F1, endo-beta-N-acetylglucosaminidase F

Endo F1 cleaves Asparagine-linked high mannose and some hybrid oligosaccharides. Core fucosylation reduces the activity by 50 fold. Endoglycosidase F1 will hydrolyze sulfate containing high-mannose chains. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. In contrast, PNGase F removes the oligosaccharide intact.

Additional Endo F Products
Endoglycosidase F2 releases biantennary and high mannose glycans (at a 40X reduced rate)
Endoglycosidase F3 will release triantennarry and fucosylated biantennary N-glycans
The Endo F Multi-Kit includes 20 µLs of each of the Endo F enzymes and their buffers.

Endo F1 Specifictity Cleaves all asparagine-linked high mannose and some hybrid oligosaccharides

Contents
60 µl aliquot of enzyme (1 U) in 20 mM Tris-HCl, pH 7.5

Included with 20 µL and 60 µL pack sizes:
5x Reaction Buffer – 250 mM sodium phosphate, pH 5.5

Specific Activity >16 U/mg
Activity >17 U/ml

Molecular weight 32,000 daltons

Suggested usage
1. Add up to 200 µg of glycoprotein to an Eppendorf tube. Adjust to 38 µl final volume with de-ionized water.
2. Add 10 µl 5x Reaction Buffer 5.5
3. Add 2.0 µl of Endo F1. Incubate 1 hour at 37ˆC.

Specific Activity
Defined as the amount of enzyme required to catalyze the release of N-linked oligosaccharides from 1 micromole of denatured Ribonuclease B (RNase B) in 1 minute at 37˚C, pH 5.5. Cleavage is monitored by SDS-PAGE (cleaved RNase B migrates faster).

Storage Store enzyme at 4˚C.

Stability Stable at least 12 months when stored properly. Several days exposure to ambient tempertures will not reduce activity.

Purity Endoglycosidase F1 is tested for contaminating protease as follows; 10 μg of denatured BSA is incubated for 24 hours at 37oC with 2 μL of enzyme. SDS-PAGE analysis of the treated BSA shows no evidence of degradation.

The production host strain has been extensively tested and does not produce any detectable glycosidases.
