Sambucus nigra Lectin (SNA/EBL I+II) - Separopore® 6B SuperTrap™ Cartridge

Product Description

Affinity purified Sambucus nigra lectin (EBL I+II, also known as SNA) is is composed of two ricin-related lectins. EBL I+II is a tetrameric glycoprotein with a recognition of the Neu5Ac(α2-6)Gal or GalNAc linkage in glycoconjugates.EBL I+II is not blood group specific but it does agglutinate type A erythrocytes more strongly than either B or O cells. Trypsin treated erythrocytes react better than untreated cells. Neuraminidase treated erythrocytes react with this lectin due to the presence of terminal galactose resides. SNA has a broad specificity for both α- and β-linked galactose, as well as unrelated sugars such as fucose. It has been determined that the lectin does not bind to glycoproteins or glycolipids containing only terminal α(2,3)-linked sialic acid residues.EBL I is composed of an A-chain with enzymatic activity and a B-chain with carbohydrate-binding activity. EBL II consists only of carbohydrate-binding B-chains. EBL I+II induces caspase-dependent apoptosis at low concentrations (nM) order, leading to typical symptoms of cell death in sensitive cells. This effect seems independent from the catalytic activity of the A-chain, but depends on the carbohydrate binding B-chain.bioWORLD produces crosslinked 6B Separopore® appropriately coupled to Sambucus nigra Lectin (SNA/EBL I+II) to provide a fast flow cartridge which can trap affinity bound material and retain it during washing, followed by elution of affinity purified material. bioWORLD’s SuperTrap cartridges of varies matrices are proven highly effective in protein chromatography.
