Phaseolus vulgaris E (PHA-E) (TRITC)

Pure Phaseolus vulgaris-E4 lectin (PHA-E) from red kidney bean, TRITC 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: PHA-E recognizes a complex branched chain oligosaccharide structure.||Inhibitory Carbohydrate: Not inhibited by simple sugars.||Activity: Less than 5ug/ml will agglutinate type O human erythrocytes. Less than 0.5mg/ml will agglutinate neuraminidase treated erythrocytes.||Chemical Used for Conjugation: TRITC||Storage and Stability:|May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months at -20°C. 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. TRITC conjugates are sensitive to light.
