α2-3,6,8 Neuraminidase catalyzes the hydrolysis of α2-3, α2-6, and α2-8 linked sialic acid residues from glycoproteins and oligosaccharides.

  • Recombinant enzyme with no detectable endoglycosidase or other exoglycosidases contaminating activities
  • Acts on both Neu5Ac and Neu5Gc
  • Fast digestion, removal of sialic acids in 5 minutes


 
Neuraminidase is the common name for Acetyl-neuraminyl hydrolase (Sialidase). This Neuraminidase catalyzes the hydrolysis of α2-3, α2-6, and α2-8 linked N-acetylneuraminic acid residues from glycoproteins and oligosaccharides.

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to cleave > 95% of the terminal α-Neu5Ac from 1 nmol Neu5Acα2-3Galβ1-3GlcNAcβ1-3Galβ1-4Glc-7-amino-4-methyl-coumarin (AMC), in 5 minutes at 37°C in a total reaction volume of 10 µl.

Reaction Conditions

1X GlycoBuffer 1
Incubate at 37°C

1X GlycoBuffer 1
5 mM CaCl2
50 mM sodium acetate
(pH 5.5 @ 25°C)

Storage Buffer

50 mM NaCl
20 mM Tris-HCl
5 mM EDTA
pH 7.5 @ 25°C

Heat Inactivation

65°C for 10 minutes

Molecular Weight
