Sambucus nigra lectin (EBL II/SNA II) isaffinity purified from elderberry bark. This lectin is a glycoprotein containing 7.8% carbohydrate and is not blood group specific. It is composed of two subunits and has a molecular weight of 140,000. EBL II has a specificity for carbohydrates containing terminal N-acetylgalactosamine and galactose residues. The blood group A-active trisaccharide containing L-fucosyl group linked alpha1-2 to galactose is 10-fold lesser as an inhibitor than the parent oligosaccharide (GalNAc alpha1-3Gal), which suggests steric hindrance to binding by the alpha-L-fucosyl group and explains the failure of the lectin to exhibit blood group A specificity. EBL II induces caspase-dependent apoptosis at low concentrations (nM) order, leading to typical symptoms of cell death in sensitive cells. This effect seems dependent on the carbohydrate binding B-chain.||Source:|Elderberry||Blood Specificity:|B > A > O||Sugar Specificity:|N-Acetylgalactosamine > Galactose||Inhibitory Carbohydrate:|Lactose > beta-Galactose||Storage and Stability:|Lyophilized powder may be stored at -20°C.
