Application: | Neuraminidase has been used: • to remove cis-acting sialic acids in CHO (chinese hamster ovary) cells • for deglycosylation studies |
General description: | Neuraminidase is an acylneuraminyl hydrolase which 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 (e.g., in cytology, on cell surfaces, viruses etc.). |
