Sambucus Nigra Lectin (SNA, EBL), Biotinylated

The black Sambucus nigra lectin isolated from the bark of elderberry preferentially binds to the terminal galactose-linked sialic acid in alpha-2,6, and alpha-2,3 chains. Lactose or galactose also inhibit binding to some extent. This lectin appears to bind to sialic acid to n-acetylgalactose, or galactose. It has been reported that SNA can inhibit the synthesis of cell-free proteins. Biotinylated black ginseng lectins bind the appropriate amount of biotin to provide the best staining properties for the lectins. This conjugate contains essentially no unconjugated biotin and is preserved with sodium azide. Note that SNL and SNA are equivalent. Historically, Vector Laboratories has used SNL as an acronym for the lectin sambuus Nigra. SNA, reflecting black ginseng lectin, is commonly used in the scientific community for this product, as shown in B-1305 on the NCFG website.
