α2-3,6,8,9 Neuraminidase A is a broad specificity sialidase, which cleaves linear and branched non-reducing terminal sialic acid residues from glycoproteins, glycopeptides, and oligosaccharides. It can be used for glycan analysis and characterization and intact glycoprotein remodeling, in vitro and in vivo.

  • Recombinant enzyme with no detectable endoglycosidase or other exoglycosidases contaminating activities
  • Acts on both Neu5Ac and Neu5Gc
  • Double digest with other exoglycosidases and endoglycosidases
  • Tolerant of moderate levels (0.5-1.0%) of detergents
  • ≥95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability for up to 24 months


 
Neuraminidase is the common name for Acetyl-neuraminyl hydrolase (Sialidase). α2-3,6,8,9 Neuraminidase A catalyzes the hydrolysis of all linear and branched non-reducing terminal sialic acid residues from glycoproteins and oligosaccharides. The enzyme releases α2-3 and α2-6 linkages at a slightly higher rate than α2-8 and α2-9 linkages.

Specificity


Detailed Specificity
α2-3,6,8,9 Neuraminidase A will cleave branched sialic acid residues that are linked to an internal residue. This oligosaccharide from fetuin is an example of a side-branch sialic acid residue that can efficiently be cleaved (1).


Product Source

Notes
  • Reactions may be scaled-up linearly to accommodate larger reaction volumes.
  • The amount of exoglycosidase enzyme required varies when different substrates are used. Start with 1–2 μl for 1 μg of glycoprotein or 100 nM of oligosaccharide for one hour in a 10–25 μl reaction. If there is still undigested material, let the reaction go overnight.
  • Higher concentrations of enzyme as well as longer incubation times may be necessary for cleavage of branched structures.
