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. Source: Sambucus nigra (Elderberry bark) Form: Supplied as a liquid in PBS, 7.3. Labeled with Biotin. Concentration: ~1mg/ml Carbohydrate Specificity: NANA a(2,6)GalNAc>GalNAc=lactose>galactose NANA a(2,6) galactose Carbohydrate Specificity: GalNAc>Gal Inhibitory Carbohydrate: High concentrtion Lactose>b-Galactose Activity: SNA-II agglutinates animal and human erythrocytes. Lectin has a slight preference for type B over A and O erythrocytes. Storage and Stability: May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
