Description

General description

Note: 1 mU = 1 milliunit.

Recombinant, Clostridium perfringens α2-3,6-Neuraminidase expressed in E. coli. Catalyzes the hydrolysis of non-reducing terminal α2,3 and α2,6 unbranched sialic acid residues from complex carbohydrates and glycoproteins. This enzyme does not exhibit activity on α2,8 or branched sialic acids.

Application

Recommended reaction buffer: 50 mM sodium phosphate buffer, pH 6.0

Warning

Toxicity: Harmful (C)

Unit Definition

One unit is defined as the amount of enzyme that will catalyze the release of 1 µmol of methylumbelliferone from 2ʹ-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic Acid (Cat. No. 474495) per min at 37°C, pH 5.0.

Physical form

In 25 mM NaCl, 20 mM Tris-HCl, pH 7.5.
