Amaranthus caudatus Lectin (ACL/ACA) - Biotinylated

Affinity-purified Amaranthus caudatus (ACL/ACA) is a dimer glycoprotein made up of two subunits. ACL has preferential specificity to oligosaccharides containing the galactosyl disaccharide Galβ3GalNAc. ACL tolerates sialic acid substitution at the 3 positions of galactose in the “T” antigen. It does not have specificity for blood groups but does have a higher affinity for type O erythrocytes over B and A.

Biotin is a small molecule involved in a wide range of metabolic processes. This ligand forms a complex with Avidin and Streptavidin, resulting in the strongest non-covalent protein-ligand interaction known. Biotinylated ACL has an appropriate amount of biotin bound to provide optimum detection characteristics when using an Avidin-HRP or Streptavidin-HRP conjugate. Biotinylated lectins allow for more sensitive detection in ELISA and Western-blotting applications.

Recommended Usage: Recommended dilution is 0.5 – 10 µg/ml in 1XPBS. Less than 0.5 µg/ml of ACL can agglutinate neuraminidase treated human erythrocyte.

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
