Descripción general
Neuraminidase hydrolyzes terminal N- or O-acylneuraminic acids which are α2,3-, α2,6-, or α2,8-linked (rate: α2,6 > α2,3 > α2,8) to oligosaccharides, polysaccharides, mucopolysaccharides, glycoproteins, and glycolipids. Noteworthy, for the hydrolysis of glycolipids, the presence of a detergent is necessary. Because of the broad substrate specificity, the enzyme is very well suited for the complete removal of sialic acids from glycoconjugates of a wide variety of biological materials.
Especificidad
Cleaves terminal sialic-acid residues that are α2,3-, α2,6-, or α2,8-linked to Gal, GlcNAc, GalNAc, AcNeu, GlcNeu, oligosaccharides, glycolipids, or glycoproteins. Relative rate of cleavage is α2,6 >α2,3 >α2,8, determined on bonds in tri- and tetrasaccharides.
Aplicación
- cell surface lectin array analysis.
- hemagglutination assays.
- cell adhesion assay.
For the hydrolysis of glycolipids, the presence of a detergent is necessary. Because of the broad substrate specificity, the enzyme is very well suited for the complete removal of sialic acids from glycoconjugates of a wide variety of biological materials.
Neuraminidase has been used for the:
- detection of the cell surface glycosylations in human anaplastic large cell lymphoma cells
- release of sialic acid from cells
- antibody-overlay lectin microarray

The serum half-life, biological activity, and solubility of many recombinant glycoproteins depend on their sialylation. Monitoring glycoprotein sialylation during cell culture manufacturing is, therefore, critical to ensure product efficacy and safety. Here a high-throughput method for semi-quantitative fingerprinting of glycoprotein
