Urtica dioica (UDA) (Biotin)

Purified Urtica dioica lectin (UDA), Biotin 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:|N-Acetylglucosamine||Inhibitory Carbohydrate:|Oligomers of b(1,4)-linked N-Acetylglucosamine.||Activity:|Less than 65ug/ml will agglutinate human type A1 and O erythrocytes. Less than 15ug/ml will agglutinate neuraminidase treated cells.||Chemical Used for Conjugation:|Biotinyl N-hydroxysuccinimide ester (BNOHSE)||Storage and Stability:|Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C.
