Aleuria aurantia (Orange peel fungus) Lectin (AAL) - Pure

Product Description
Lectin AAL is isolated from orange peel fungus (Aleuria aurantia). AAL is a diamer of two identical subunits with a molecular weight of 72,000. Each subunit has five carbohydrate-binding sites that recognize and bind specifically to fucose and terminal fucose residues on complex oligosaccharides and glycoconjugates. AAL shows high affinity for Fucα6GlcNAc in the core of N-glycans and gives an elution of 100 mM L-fucose. AAL also reversibly binds fucose attached to nucleic acids. This lectin has an isoelectric point of pH 9 and non-specific blood group.

AAL comes in lyophilized powder form and is stable for more than three years from production date when stored below -20˚C. AAL is available in chromatographically purified, affinity purified and conjugated to various fluorophores, biotin, HRP and immobilized to Separopore (agarose) matrix.

Applications:
Studies of glycoproteins and glycolipids
Purification of membrane proteins and receptors
Affinity chromatography
Subcellular localization (Histochemistry)
Agglutination studies
ELISA assays
