Artocarpus integrifolia Lectin (AIA) - AP (Alkaline Phosphatase)
Price: Regular price $181.13
Product Description
Artocarpus integrifolia Lectin (AIA) is purified by affinity chromatography and is tetrameric two-chain structure consisting of four identical protomers with an isoelectric point of pH 7.8. The lectin has specificity for blood group types O (+SA) and T. Jacalin is considered a galactose-specific lectin and elutes with galactose or melibiose. A post-translational proteolytic modification of Jacalin gives the lectin a novel carbohydrate-binding site involving the N terminus of the α-chain. The protein’s structure explains its carbohydrate-binding specificity of T-antigen disaccharide Galß1,3GalNAc. Potent inhibitors of jacalin include D-galactose, ß-Met-Gal and 2-deoxy-α-D-galactose. This product comes in a stable lyophilized form.
Alkaline phosphatase (AP) is conjugated to Artocarpus integrifolia (Jacalin) Lectin (AIA) to show the binding of AIA in many applications including Western blotting and ELISA. Alkaline phosphatase is a large protein (140 kDa) that catalyzes the hydrolysis of phosphate groups from a substrate resulting in a colored or fluorescent product. The optimal enzymatic activity of this protein is between pH 8 and 10, and its reaction rate remains linear, improving sensitivity over time.
Recommended Usage: Recommended dilutions 0.5 – 10 µg / ml in 1XPBS pH 7.4. Less than 1 µg / ml will agglutinate human erythrocyte.
