Euonymus europaeus lectin or agglutinin (EEL/EEA) is affinity purified and is a homodimer consisting of subunits of 17 kDa linked by disulfide bonds. EEL consists of six closely related lectins (isoforms). Previous reports of higher molecular weight and overestimated carbohydrate percentage are attributed to lectin-glycoprotein complexes and not the Euonymus europaeus lectin itself. This lectin is characteristic of its erythrocyte agglutinating properties and specificity for blood groups B and H. It has a stronger binding of the B oligosaccharide with higher affinity for B-type II in comparison to H structures with Galα1,3 structures. Conversely, it has also been reported that EEL has preferential binding to H blood group-related carbohydrates over the B bloof group due to similarities in the β-trefoil fold found in EEL and ricin B-like lectins. EEL's general pattern allows it to interact with both α-fucose residues on B and H blood groups as well as high-mannose N-type glycans. This lectin binds to endothelial cells from human and non-human sources and recognizes carbohydrate structures on the surface of stimulated murine peritoneal lymphoid cells. EEL also has applications as a endothelial/epithelial marker in canine tissues and has been studied in Kashin-Beck disease. 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 EEL 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.
