QA Bio Inc Neuraminidase Au - Alpha (2-3,6,8,9) - 200 µls
Supplier: QA Bio Inc ES001200
Alpha (2-3,6,8,9) Neuraminidase Au cleaves all cleaves all non-reducing terminal sialic acid residues from complex carbohydrates and glycoproteins. The relative cleavage rates for different linkages are: α(2-6) > α(2-3) > α(2-8), α(2-9). • In addition, the enzyme will cleave branched sialic acids (linked to an internal residue). This property makes it unique among neuraminidases. High concentrations of enzymes and prolonged incubation times may be required for cleaving branched residues. To cleave only non- reducing terminal α(2-3) unbranched sialic acid residues, use Neuraminidase SP, part number E-S007. • Source: recombinant from Arthrobacter ureafaciens in E. Coli. • EC 3.2.1.18 • Contents: Neuraminidase in 20 mM Tris-HCl, 25 mM NaCl, pH 7.5 / 5x Reaction Buffer 250 mM sodium phosphate, pH 6.0 • Specific Activity >135 U/mg • Activity>5 U/ml • Molecular weight 70,000 daltons • pH range 4.5-7, optimum 6.0
