Aleuria Aurantia Lectin (AAL), Biotinylated, 1 mg. Unlike Ulex europaeus and Lotus tetragonolobus lectins which prefer (alpha-1,2) linked fucose residues, Aleuria aurantia lectin binds preferentially to fucose linked (alpha-1,6) to N-acetylglucosamine or to fucose linked (alpha-1,3) to N-acetyllactosamine related structures. AAL also reversibly binds fucose attached to nucleic acids. Biotinylated Aleuria Aurantia Lectin 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.
