Sambucus nigra Lectin (SNA/EBL I) - Pure

Sambucus nigra Lectin (SNA/EBL I) is an isolectin, isolated from elderberry bark and purified via affinity chromatography. As a type 2 ribosome-inactivating protein, it consists of an A-chain with enzymatic activity and a B-chain with carbohydrate-binding activity. SNA I specifically targets α2,6-linked sialic acid residues and elutes with lactose. At low concentrations, it can induce apoptosis through a caspase-dependent pathway, an effect that relies on the carbohydrate binding of the B-chain and is independent of the A-chain's catalytic activity. SNA I inhibit cell free protein synthesis.

Recommended Usage: Recommended dilutions of 0.5 – 10 μg in 1XPBS. 2 – 10 μg of SNA I can agglutinate human, rabbit or porcine erythrocytes.

Storage Instruction: To prevent degradation and avoid repeated freeze-thaw cycles, aliquot your product into small, single-use volumes and store them at -20°C
