Product Overview:
VC1784 (neuraminidase) was chromatographically purified from V. cholerae.
Neuraminidase is used to cleave N-acetylneuraminic acid (sialic acid) from a variety of glycoproteins. Sialic acids are a family of N- and O-substituted derivatives of neuramic acid. Some of the more common and diverse known functions of sialic acids include the binding of hormones, toxins, and viruses, the masking of surface antigens, the modification of the circulating half-lives of red blood cells and glycoproteins, and the maintenance of surface negative charge.

Sterile-filtered aqueous solution, pH 5.5, containing 0.15 M sodium chloride and 4 mM calcium chloride and no preservatives.
Specific Activity: 1–5 units/mg protein.
Unit Definition:
One unit will liberate 1.0 mmole of N-acetylneuraminic acid per minute at pH 5.0 at 37 centigrade using NAN-lactose as the substrate.
Neurminidase is used as a cell-surface probe for glycoconjugate distribution and in substrate specificity studies.
It remains active for at least 2 years.
Store at 2-8 centigrade
