NEU2 Protein, Human, Recombinant (His Tag)

Human sialidase 2 (NEU2) is a cytoplasmic sialidase that degrades sialyl glycoconjugates, including glycoproteins and gangliosides, via hydrolysis of terminal sialic acids to produce asialo-type molecules. It belongs to a family of glycohydrolytic enzymes that remove sialic acid residues from glycoproteins and glycolipids. NEU2 expression as assessed by quantitative real-time PCR was found to be extremely low or undetectable in many human tissues and cells, with notable exceptions like the placenta and testis. The human cytosolic sialidase NEU2 is the only mammalian enzyme structurally characterized and represents a valuable model to study the specificity of novel NA inhibitory drugs. Diseases associated with NEU2 include Galactosialidosis and Discrete Subaortic Stenosis.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 20 % glycerol, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
