Endoglycosidase F1 will hydrolyze sulfate containing high-mannose chains. It cleaves between the two N-acetylglucosamine residues in the Product DescriptionEndo F1 cleaves Asparagine-linked high mannose and some hybrid oligosaccharides. Core fucosylation reduces the activity by 50 fold. Endoglycosidase F1 will hydrolyze sulfate containing high-mannose chains. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. In contrast, PNGase F removes the oligosaccharide intact.Molecular weight 32,000 daltonsContents60 µl aliquot of enzyme (1 U) in 20 mM Tris-HCl, pH 7.5Included with 20 µL and 60 µL pack sizes:5x Reaction Buffer – 250 mM sodium phosphate, pH 5.5Specific ActivityDefined as the amount of enzyme required to catalyze the release of N-linked oligosaccharides from 1 micromole of denatured Ribonuclease B (RNase B) in 1 minute at 37°C, pH 5.5. Cleavage is monitored by SDS-PAGE (cleaved RNase B migrates faster).FormulationThe enzyme is provided as a sterile-filtered solution in 20 mM Tris-HCl, pH 7.5StabilitySeveral days exposure to ambient temperatures will not reduce activity. Stable at least 12 months when stored properly. SpecificityEndo F1 cleaves Asparagine-linked high mannose or hybrid oligosaccharides. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. In contrast, PNGase F removes the oligosaccharide intact. Quality & PurityEndo F1 is tested for contaminating protease as follows: 10 µg of denatured BSA is incubated at 37°C for 24 hours with 2 µl of enzyme. SDS-PAGE analysis of the treated BSA shows no evidence of degradation. The production host strain has been extensively tested and does not produce any detectable glycosidases.Directions for use1. Add up to 200 µg of glycoprotein to an Eppendorf tube. Adjust to 38 µl final volume with de-ionized water.2. Add 10 µl 5x Reaction Buffer 5.53. Add 2.0 µl of Endo F1 to the reaction. Incubate 1 hour or more at 37°C.Monitor cleavage by SDS-PAGE... Read More | Endothelin 3 (ET3) belongs to endothelin peptide family, which includes three members, ET-1, -2 and -3. These are 21-amino acid peptides, which are synthesized as precursors. They are converted to biologically active peptides, after being cleaved by proteases. There are two endothelin receptors Endothelin 3 (ET3) belongs to endothelin peptide family, which includes three members, ET-1, -2 and -3. These are 21-amino acid peptides, which are synthesized as precursors. They are converted to biologically active peptides, after being cleaved by proteases. There are two endothelin receptors called ETRA and ETRB, and ET3 binds to ETRB. It is localized to human intestine and colon.Application：Endothelin 3 has also been used as a ligand for endothelin receptor type B (EDNRB) in ex vivo enteric NCC (eNCC) migration assays. Endothelin 3 human, rat has been used for culturing neural tube explant culture, and the pharmacological study of endothelin receptors... Read More | Product Characteristics UNI-StabilPLUS is a universal stabilizer for the dilution and stabilization of both Horseradish Peroxidase (HRP) and Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enablesProduct Characteristics UNI-StabilPLUS is a universal stabilizer for the dilution and stabilization of both Horseradish Peroxidase (HRP) and Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of pre-diluted, ready-to-use conjugates, minimizing assay errors in dilution. Superior stabilization of HRP and AP conjugated antibodies in low as well as high protein dilutions is seen, when using UNI-StabilPLUS. When tested with AP conjugated antibody stability is seen as follows: • at least 3 years at 2-8 °C • at least 2 years at room temperature • at least 4 weeks at 37 °C When tested with HRP conjugated antibody stability is seen as follows: • at least 2 years at 2-8 °C • at least 1 years at room temperature • at least 2 weeks at 37 °CUNI-StabilPLUS is recommended for the dilution of antibodies directed against rabbit immunoglobulins unlike HRP-StabilPLUS (cat. no. H494387) and Antibody Enhancer (cat. no. A494276).Composition & Properties UNI-StabilPLUS is a ready-to use buffer that appears as an opaque solution. The product is based on a mild acid Tris buffer containing proprietary stabilizing components. UNI-StabilPLUS contains neither BSA, nor other material from bovine serum, no azide, mercury or other toxic components.Working Procedure 1.Make a series of dilutions of the HRP- or AP conjugated protein in UNI-StabilPLUS in order to determine the optimal dilution. 2.Run the assay as usual or store the diluted conjugated protein preferably at 2-8 °C.Tips & Tricks • Avoid using phosphate buffers for AP-conjugated antibody assays. We recommend the use of Tris/HCl, Tween as the washing buffer, instead of a PBS buffer which will reduce signal significantly. • For extended stability of HRP conjugated antibodies, HRP-StabilPLUS (cat. no. H494387) is recommended. Handling & Storage • Store solution at 2-8 °C... Read More |
