| Description | Pure Limulus polyphemus lectin (LPA) from horseshoe crab. 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: Sialic Acid (N-Acetyl neuraminic acid) Inhibitory Carbohydrate: N-Acetylneuraminic acid and N-Glycolylneuraminic acid Activity: 10-20ug/ml will agglutinate type O human erythrocytes. As much as 100ug/ml may be necessary to agglutinate type A or B cells. Note: Calcium is required for binding. The addition of EDTA may be used to inhibit binding. LPA is composed of 18-20 noncovalently bound subunits and may precipitate if frozen. Clarify by low speed centrifugation. 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 after receipt 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. | ||
