Pure Phaseolus lunatus lectin (LBA) from lima bean, FITC conjugated. 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. Carbohydrate Specificity: GalNAc alpha(1,3) [Fuc alpha(1,2)] Gal Inhibitory Carbohydrate: N-Acetylgalactosamine Activity: Less than 60ug/ml will agglutinate type A1 human erythrocytes. More than 200ug/ml is required to agglutinate type A2 cells. Chemical Used for Conjugation: FITC Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. FITC conjugates are sensitive to light.
