Sambucus nigra (SNA I) (Biotin)

Lectins are derived from the extracts of plants, animals, viruses and microorganisms. They are known to agglutinate red blood cells. These agglutinins can select cell types according to blood group activities utilizing sugar-binding mechanisms. Lectins form precipitates with glycoconjugates and are useful for identifying or separating oligosaccharides with identical sugar compositions such as galactose, mannose or glucose. Sambucus nigra lectin (SNA-1) agglutinates animal and human erythrocytes. The lectin has a slight preference for type A over types B and O erythrocytes.||Carbohydrate Specificity: |NANA (Neu5Ac a(2,6)Gal/GalNAc)||Inhibitory Carbohydrate:|High concentration Lactose > b-Galactose.||Storage and Stability:|Aliquot to avoid repeated freezing and thawing.
