Soybean agglutinin (SBA), Biotinylated

Soybean Agglutinin (SBA), Biotinylated, 5 mg, preferentially binds to oligosaccharide structures with terminal alpha- or beta-linked N-acetylgalactosamine, and to a lesser extent, galactose residues. Binding can be blocked by substitutions on penultimate sugars, such as fucose attached to the penultimate galactose in blood group B substance. Biotinylated Soybean agglutinin 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.
