Product Description
The receptor sugar for WGA is N-acetylglucosamine, with preferential binding to dimers and trimers of this sugar. WGA can bind oligosaccharides containing terminal N-acetylglucosamine or chitobiose, structures which are common to many serum and membrane glycoproteins. Bacterial cell wall peptidoglycans, chitin, cartilage glycosaminoglycans, and glycolipids can also bind WGA. Biotinylated WGA has an appropriate number of biotins bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated biotins and is preserved with sodium azide. Source: Wheat germ Blood Specificity: A, B, O Carbohydrate Specificity: N-Acetylglucosamine Inhibitory Carbohydrate: Chitin Hydrolysate or N-Acetylglucosamine Divalent Ions: None Applications: Immunohistochemistry / Immunocytochemistry, Immunofluorescence, Blotting Applications, Elispot, ELISAs, Glycobiology Recommended Dilutions: For most applications we recommend a freshly prepared working solution of 5-20ug/ml in the above buffer.
