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 | Product introduction：The additive contains a variety of cytokines, human albumin and other components. In order to ensure the activity, it is recommended that the additive part be thawed once and then sub packaged and frozen again. It is not advisable to freeze and thaw repeatedly. The Product introduction：The additive contains a variety of cytokines, human albumin and other components. In order to ensure the activity, it is recommended that the additive part be thawed once and then sub packaged and frozen again. It is not advisable to freeze and thaw repeatedly. The product contains no animal serum or animal serum components, no animal protein components, and no antibiotics.Matters needing attention：1. try to reduce the number of repeated freezing and thawing to avoid efficiency decline. 2. it is not suitable to place it at room temperature for a long time. 3. pay attention to aseptic operation and try to avoid pollution. 4. please wear experimental clothes and disposable gloves for operationScope of application：Cell culture additives...

HLA-DRA binds peptides derived from antigens which access the endocytic route of antigen presenting cells (APC) Purity: >90%, by SDS-PAGE visualized with Coomassie® Blue Staining. Description: Major histocompatibility complex, class II, DR alpha (HLA-DRA) belongs to the MHC class II family. HLA-DRA binds peptides derived from antigens which access the endocytic route of antigen presenting cells (APC) and presents them on the cell surface for identification by the CD4 T-cells. The peptide binding cleft accommodates peptides of 10-30 residues. The peptides presented by MHC class II molecules are generated mainly by degradation of proteins which access the endocytic route, where they are processed by lysosomal proteases and other hydrolases...

Stimulates AMPK phosphorylation and activation in the liver and the skeletal muscle, enhancing glucose utilization and fatty-acid combustion. Antagonizes TNF-alpha by negatively regulating its expression in various tissues such as liver and macrophages, and also by counteracting its effects. Inhibits endothelial NF-kappa-B signaling through a cAMP-dependent pathway. May play a role in cell growth, angiogenesis and tissue remodeling by binding and sequestering various growth factors with distinct binding affinities, depending on the type of complex, LMW, MMW or HMW.Post-translationalHydroxylated Lys-33 was not identified in PubMed:16497731, probably due to poor representation of the N-terminal peptide in mass fingerprinting. HMW complexes are more extensively glycosylated than smaller oligomers. Hydroxylation and glycosylation of the lysine residues within the collagene-like domain of adiponectin seem to be critically involved in regulating the formation and/or secretion of HMW complexes and consequently contribute to the insulin-sensitizing activity of adiponectin in hepatocytes. O-glycosylated. Not N-glycosylated. O-linked glycans on hydroxylysines consist of Glc-Gal disaccharides bound to the oxygen atom of post-translationally added hydroxyl groups. Sialylated to varying degrees depending on tissue. Thr-22 appears to be the major site of sialylation. Higher sialylation found in SGBS adipocytes than in HEK fibroblasts. Sialylation is not required neither for heterodimerization nor for secretion. Not sialylated on the glycosylated hydroxylysines. Desialylated forms are rapidly cleared from the circulation...
