It also will cleave high mannose glycans but at a 40x reduced rate. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, Product DescriptionEndo F2 cleaves N-linked (asparagine-linked) biantennary oligosaccharides from glycoproteins. It also will cleave high mannose glycans but at a 40x reduced rate. 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.Endoglycosidase F2 is less sensitive to protein conformation than PNGase F and is therefore more suitable for deglycosylation of native proteins. However, for optimal results, denaturation of the glycoprotein is recommended.Contents60 µl aliquot of enzyme (0.3 U) in 10 mM sodium acetate 25mM NaCl, pH 4.5Included with 20 µL and 60 µL pack sizes:5x Reaction Buffer – 250 mM sodium acetate, pH 4.5Molecular weight 32,000 daltonsSpecific Activity Defined as the amount of enzyme required to catalyze the release of N-linked oligosaccharides from 1 micromole of denatured porcine fibrinogen in 1 minute at 37°C, pH 5.5. Cleavage is monitored by SDS-PAGE (cleaved fibrinogen migrates faster).Formulation The enzyme is provided as a sterile-filtered solution in 10 mM sodium acetate, 25mM NaCl, pH 4.5Specificity Endo F2 cleaves Asparagine-linked biantennary and high mannose glycans (at a 40X reduced rate). 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. Endoglycosidase F2 is less sensitive to protein conformation than PNGase F and is therefore more suitable for deglycosylation of native proteins. However for optimal results, denaturation of the glycoprotein is recommended.Quality & Purity Endo F2 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.Stability Several days exposure to ambient temperatures will not reduce activity. Stable at least 12 months when stored properly.Directions for use 1. 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 4.5 3. Add 2.0 µl of Endo F2 to the reaction. Incubate 1 hour at 37°C. Monitor cleavage by SDS-PAGEThe production host strain has been extensively tested and does not produce any detectable glycosidases...

It is derived from a 34 kDa inactive precursor zymogen, trypsinogen, after enzymatic removal of an N-terminal 6-amino acid leader sequence resulting in the 23.8 kDa Trypsin is a pancreatic serine protease with substrate specificity based upon positively charged lysine and arginine side chains. It is derived from a 34 kDa inactive precursor zymogen, trypsinogen, after enzymatic removal of an N-terminal 6-amino acid leader sequence resulting in the 23.8 kDa trypsin molecule. The optimum pH is 8.0. Trypsin is inhibited by organophosphorus compounds such as diisopropylfluorophosphate and natural inhibitors from pancreas. Soybean, lima bean, and egg white are also sources of natural inhibitors. Trypsin cleaves amide and ester bonds of Arg and Lys. The Aladdin Sequencing Grade Trypsin has been further purified to remove trace contaminating proteases and autolysis products which could interfere in trypsin digestion experiments, and exhibits a single band on PAGE.Trypsin is a serine protease used to hydrolyze proteins. Trypsin from bovine pancreas has a molecular weight of 23.8 kDa. Trypsins are used for the re-suspension of cells during cell culture and in proteomics research for the digestion of various proteins... Read More |
