Description

Artocarpus integrifolia Lectin (AIA) is purified by affinity chromatography and features a tetrameric two-chain structure composed of four identical protomers, with an isoelectric point of pH 7.8. This lectin is specific for blood group types O (+SA) and T. Jacalin is classified as a galactose-specific lectin, eluting with galactose or melibiose. A post-translational proteolytic modification introduces a novel carbohydrate-binding site at the N terminus of the α-chain. The protein's structure accounts for its binding specificity to the T-antigen disaccharide Galß1,3GalNAc. Potent inhibitors of jacalin include D-galactose, ß-Met-Gal, and 2-deoxy-α-D-galactose. This product is available in a stable lyophilized form.

Recommended Usage: Recommended dilutions 0.5 – 10 µg / ml in 1XPBS. Less than 0.5 µg / ml will agglutinate human erythrocytes.

Storage Instruction: To prevent degradation and avoid repeated freeze-thaw cycles, aliquot your product into small, single-use volumes and store them at -20°C

Application

Immunohistochemistry, Immunocytochemistry, Cell typing, Western blotting, IgG purification. Bioconjugation. Cancer biomarker. AIDS Research. Glycobiology.
