Sambucus nigra lectin (SNA, EBL), Unconjugated

Sambucus Nigra Lectin (SNA, EBL), Unconjugated, 5 mg, isolated from elderberry bark, binds preferentially to sialic acid attached to terminal galactose in alpha-2,6 and, to a lesser degree, alpha-2,3 linkage. Binding is also inhibited to some extent by lactose or galactose. This lectin does not appear to bind sialic acid linked to N-acetylgalactosamine. SNA has been reported to inhibit cell-free protein synthesis.
