approximately 100 U/mg protein at +37°C and pH 5.0 with N-acetyl-neuraminosyl-D-lactose as the substrate.
Egyediség
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 α2,3 >α2,8 = α2,6, determined on bonds in tri- and tetrasaccharides.
Alkalmazás
Neuraminidase (Sialidase) has been used to desialylate transferrin in order to study its isoforms in human serum.
Use Neuraminidase to hydrolyze terminal N- or 0-acylneuraminic acids which are α2,3-, α2,6-, or α2,8-linked (rate α2,3: > α2,6 = α2,8) to oligosaccharides, polysaccharides, mucopolysaccharides, glycoproteins, and glycolipids.In contrast to the enzyme from Arthrobacter ureafaciens, neuraminidase from Clostridium perfringens hydrolyzes α2,3-linkages faster than α2,6-linkages. α2,8-bound sialic acids area cleaved with a similar velocity compared to α2,6-bound sialic acids.
Neuraminidase is used for:
Neuraminidase is used for:
- Virus receptor studies
- Studies on the interaction of lymphocytes with tumor cells
- Cell hybridizations
- Analysis of oligosaccharides
- Analysis of glycoproteins
- Analysis of glycolipids
Biokémiai/fiziológiai hatások
Neuraminidase breaks α-ketosidic linkage between N-acetylneuraminic acid and the adjacent sugar residue.
Neuraminidase mediates apoptosis in the host cell before viral entry.
Elkészítési megjegyzés
Stabilizers: The enzyme can be stabilized by bovine serum albumin (BSA).
Storage conditions (working solution): After reconstitution in double-dist. water or sample buffer, the enzyme is stable for several weeks, stored at 2 to 8 °C; for longer storage, freezing is recommended. A stock solution may be made (e.g., at c = 5 U/100 μl). The enzyme looses approx. 50% of its activity after incubation at 37 °C for 24 hours.

Oocytes and granulosa cells closely interact with each other during follicular development, and a lack of appropriate signaling between them results in infertility. Attempts to manipulate oocyte microenvironment have been impeded by the impermeability of the blood-follicle barrier (BFB). To

Elevated concentrations of circulating low density lipoprotein (LDL) that is abnormally oxidized and desialylated is both a precursor to and a hallmark of atherosclerosis. Peripheral blood mononuclear cells (PBMCs) treated in vitro with interleukin-2 (IL-2) become lymphokine activated killer (LAK)

Capillary electrophoresis analysis of transferrin in human serum is used to assess genetic variants after desialylation with neuraminidase and iron saturation to reduce the complexity of the transferrin pattern and thus facilitate the recognition of transferrin polymorphisms. Asialo-transferrin forms are
