Sambucus nigra (SNA/EBL I)

Sambucus nigra Lectin (SNA/EBL I) is an isolectin isolated from elderberry bark and purified by affinity chromatography. SNA I belongs to the group of type 2 ribosome-inactivating proteins and is composed of an A-chain with enzymatic activity and a B-chain with carbohydrate-binding activity. It has specificity for alpha2,6-linked sialic acid residues, and elutes with the sugar lactose. SNA I can induce apoptosis through the caspase-dependent pathway at low concentrations. This effect depends on the carbohydrate binding of the B-chain and is independent from the catalytic activity of the A-chain.||Source:|Elderberry||Blood Specificity:|A > B > O||Sugar Specificity:|Sialic Acid||Inhibitory Carbohydrate:|Lactose > beta-Galactose||Storage and Stability:|Lyophilized powder may be stored at -20°C.
