| Description | Lectins are derived from the extracts of plants, animals, viruses and microorganisms and 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. Arachis hypogaea (PNA, Peanut Agglutinin), 110kD, is composed of four identical subunits of approximately 27kD each, is galactose-specific, with strong anti-T-antigen activity. T-antigen") is present in many glycoconjugates such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. PNA does not agglutinate normal human erythrocytes, but strongly agglutinates neuraminidase-treated red blood cells. The presence of Ca++ can enhance the binding of PNA to receptors. Asialo GM1 ganglioside is also thought to be a major cell surface receptor for PNA. PNA is useful in normal and tumor tissue determination for transitional mucosa malignancies. Carbohydrate Specificity: Terminal b-Galactose Inhibitory Carbohydrate: Lactose > b-Galactose. Activity: <1ug/ml will agglutinate human erythrocytes neuraminidase treatment of the cells. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. | ||
