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: beta (1,4)-linked N-Acetylglucosamine.
Inhibitory Carbohydrate: 50-60ug/ml will agglutinate type O human erythrocytes. 5-10ug/ml will agglutinate neuraminidase treated cells.
