Artocarpus integrifolia Lectin (AIA) - DyLight 488
Price: Regular price $0.00
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.
DyLight 488 is a green-fluorescent dye used to visualize the binding pattern of Artocarpus integrifolia (Jacalin) Lectin (AIA) in cellular imaging and flow cytometry. It operates effectively over a broad pH range (pH 4-9) and is brighter and more photostable than many other green-fluorescent dyes, including FITC.
Recommended Usage: Recommended dilutions 0.5 – 10 µg / ml in 1XPBS. Less than 1 µg / ml will agglutinate rabbit erythrocytes.
