Product Description

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 α1-2 to galactose is 10-fold lesser as an inhibitor than the parent oligosaccharide (GalNAc α1-3Gal), which suggests steric hindrance to binding by the α-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.

Sambucus nigra Lectin (SNA/EBL II) is labeled with tetramethylrhodamine isothiocyanate (TRITC) and has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. TRITC is a bright orange or red-fluorescent dye with excitation ideally suited to the 532-nm laser line. TRITC labeled SNA/EBL II can be used for cellular imaging applications.
