Endo F2
NEBU cloned at NEB recombinant 37 65 Heat

Product Introduction

Endo F2 is a highly specific recombinant endoglycosidase which cleaves within the chitobiose core of asparagine-linked complex biantennary and high mannose oligosaccharides from glycoproteins and glycopeptides. Endo F2 cleaves biantennary glycans at a rate approximately 20 times greater than high mannose glycans.  The activity of Endo F2 is identical on biantennary structures with and without core fucosylation.  However, Endo F2 is not active on hybrid or tri- and tetra-antennary oligosaccharides.

  • Endo F2 is tagged with a chitin binding domain (CBD) for easy removal from a reaction
  • Recombinant enzyme with no detectable exooglycosidase or other endoglycosidase contaminating activities
  • Glycerol -free for optimal performance in HPLC and mass spectrometry analysis
  • ≥95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability for up to 24 months

Unit Assay Conditions

Two fold dilutions of Endo F2 are incubated with 10 µg Porcine Fibrinogen and 1X GlycoBuffer 4 in a 10 µl reaction. The reaction mix is incubated at 37°C for 1 hour. Separation of reaction products are visualized via SDS-PAGE.

Product Notes

  1. The enzyme can be used under denaturing and non-denaturing (native) conditions. However, optimal activity occurs under non-denaturing conditions.
  2. Reactions may be scaled-up linearly to accommodate larger reaction volumes.

Tech Tips

  • Endo F2 is tagged with a chitin binding domain (CBD) for easy removal from a reaction using chitin magnetic beads (NEB #E8036 )
  • Endo F2 is typically used under non-denaturing (native) conditions, as denaturation is not necessary for optimal activity of the enzyme.
  • Concentrations of 0.5% SDS do not inhibit Endo F2 activity when used in the presence of 1% NP-40.
  • The optimal pH for cleavage of biantennary glycans is pH 4.5 (10X Glycobuffer 4)
  • Although not as optimal, cleavage can also occur at pH 6.0 (10X Glycobuffer 3).
