Endo S
Product Introduction
Endo S is an endoglycosidase specific for cleaving the N-linked glycans from the chitobiose core of the heavy chain of native IgG
- Active on native IgG
- Tagged with a chitin binding domain (CBD) for easy removal
- Recombinant enzyme with no detectable exooglycosidase or other endoglycosidases 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 12 months

Product Information
Description
Endo S is an endoglycosidase
with a uniquely high specificity for removing
N-linked glycans from the chitobiose core of the
heavy chain of native IgG (1). Endo
S is tagged with a chitin binding domain (CBD)
for easy removal from a reaction and is supplied
glycerol free for optimal performance in HPLC and
MS intensive methods.
Product Source
Endo S is cloned from Streptococcus pyogenes and overexpressed as a fusion to the chitin binding domain in E. coli.Specificity
Detailed SpecificityX = protein, peptide, Asparagine, or free glycan, as Endo S does not have a strict peptide requirement for activity. Endo S is active on a substrate with or without core α(1-6)fucosylation as well as a with or without a bisecting N-acetylglucosamine. Triantennary and tetrantennary sialyated or asialo glycans are not a substrate for Endo S (1).

Product Notes
- Recommended storage temperature is 4°C,avoid repeat freeze-thaw cycles.
- Removal of Endo S from thedeglycosylation reaction can be scaled uplinearly with larger volumes of chitin magneticbeads.
- The binding capacity of Chitin Magnetic Beads is 1 mg of CBD-tagged protein / mL of beads.
