The presence of sialic Product Descriptionalpha-L-fucoside fucohydrolase, alpha-L-fucosidase, alpha-(1-3,4) fucosidaseAlpha (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.For removing core fucose linked α-(1-6) to the core GlcNAc of a GlcNAc-GlcNAc disaccharide structure we recommend our Alpha-(1-6) Fucosidase.α(1-3, 4) Fucosidase is useful for:nbsp;nbsp;Fucose linkage determinationnbsp;nbsp;Deglycosylating glycoproteins with Lewis structuresContentsAlpha-(1-3,4)-Fucosidase in 20 mM Tris-HCl, 25 mM NaCl,(pH 7.5).Included with 20 µL and 60 µL pack sizes:5x Reaction Buffer 5.0 (250 mM sodium phosphate, pH 5.0)Molecular weight40,000 daltonsFormulationThe enzyme is provided as a sterile-filtered solution in 20 mM Tris-HCl, 25 mM NaCl pH 7.5.Suggested usage1. Add up to 1 nmole of oligosaccharide to a tube.2. Add de-ionized water to a total of 15 µl.3. Add 4 µl of 5x Reaction Buffer 5.0.4. Add 1 µl of Alpha-(1-3,4)-Fucosidase.5. Incubate for 1 hour at 37˚C.SpecifictityNon-reducing terminal branched fucose when linked alpha-(1-3) or alpha-(1-4) to GlcNAc of a Gal-GlcNAc disaccharide structure. The presence of sialic acid (but not fucose) linked to the galactose will block cleavage.Specific Activity AssayOne unit of Fucosidase activity is defined as the amount of enzyme required to cleave 1 µmole of fucose from Lewis X trisaccharide, 4-methylumbelliferyl glycoside in 1 minute at 37˚C and pH 5.0. Lewis X trisaccharide is Gal Beta-(1-4)[Fuc alpha-(1-3)]GlcNAc.PurityEach lot of α(1-3, 4) Fucosidase is tested for contaminating activities by incubating the enzyme for 24 hours at 37°C with the appropriate substrates; the detection limit of this assay is 5 µU/mL (IUB). A passing lot will have no detectable activity.For the protease assay, 10 µg of denatured BSA is incubated for 24 hours with 2 µL of enzyme. Analysis of the BSA band after SDS-PAGE should show no evidence of degradation.StabilityStable at least 12 months when stored properly. Several days exposure to ambient temperatures will not reduce activity...

In the Purity:>90%, by SDS-PAGE visualized with Coomassie® Blue Staining.Description: DCX (doublecortin, N-GST chimera)contains 2 doublecortin domains and belongs to the doublecortin family. It is highly expressed in neuronal cells of fetal brain, but not expressed in other fetal tissues. In the adult, it is highly expressed in the brain frontal lobe, but very low expression in other regions of brain, and not detected in heart, placenta, lung, liver, skeletal muscles, kidney and pancreas. DCX is a microtubule-associated protein required for initial steps of neuronal dispersion and cortex lamination during cerebral cortex development. It may act by competing with the putative neuronal protein kinase DCAMKL1 in binding to a target protein. DCX may in that way participate in a signaling pathway that is crucial for neuronal interaction before and during migration, possibly as part of a calcium ion-dependent signal transduction pathway. It may be part with LIS-1 of a overlapping, but distinct, signaling pathways that promote neuronal migration. Defects in DCX are the cause of lissencephaly X-linked type 1 and subcortical band heterotopia X-linked... Read More |
