α(1-6) Core Mannosidase cleaves unbranched non-reducing terminal mannose, α(1-6) linked to the β-linked core mannose of the conserved mannosylchitobiose core of N-linked oligosaccharides. The presence of fucose linked to the core N-acetylglucosamine has no effect on cleavage.
α(1-3,4) Fucosidase cleaves branched non-reducing terminal fucose, linked α(1-3) or α(1-4) to the N-acetylglucosamine of terminal Gal-GlcNAc disaccharide structures. The presence of sialic acid (but not fucose) linked to the galactose will block cleavage.
α(2-3,6,8,9) Sialidase Au cleaves all cleaves all non-reducing terminal sialic acid residues from complex carbohydrates and glycoproteins. The relative cleavage rates for different linkages are: α(2-6) > α(2-3) > α(2-8), α(2-9).
α(2-3,6) Sialidase Cp cleaves all non-reducing terminal non-branched α(2-3) and α(2-6) sialic acid residues from complex carbohydrates and glycoproteins. There is no detectable activity on α(2-8) or α(2-9) linkages or on branched α(2-3) or α(2-6) linkages. The relative cleavage rates for different linkages are: α(2-3) > α(2-6).
To remove 9-, 8- and 7-O-acetyl groups from released sialic acids, released glycans or glycoproteins. Used for characterisation of highly sialylated biotherapeutics such as EPO, FSH and blood clotting factors. Kit includes enzyme plus reaction buffer. Sufficient for up to 50 samples.
