-20°C""Ulex europaeus agglutinin (UEA I) is affinity purified isolated from gorse seeds and separated from crude extract by affinity chromatography. It is consists of two subunits. The lectin is a glycoprotein that has no mitogenic activity to agglutinates type O erythrocytes, and of a lesser degree to individuals with A2 erythrocytes.UEA I reacts strongly with alpha(1,2) linked fucose residues but poorly or not at all with alpha(1,3) or alpha(1,6)-linked fucose. UEA I is unable to bind internal fucose structures and the presence of an internal alpha(1,3)-linked fucose on the H type 2 oligosaccharide decreases lectin affinity for this blood group antigen by 3-fold.UEA I has been used as a marker for vascular endothelium and used to identify endothelial cells of benign vascular lesions more specifically than antibodies Factor VII-related antigen. UEA I coated magnetic beads have been used to isolate endothelial cells associated with micro-vessels for subsequent cell culture. This lectin has also been used to differentiate between angiosarcomas and epithelial tumor.||Source:|Gorse||Blood Specificity:|O > A2||Sugar Specificity:|alpha-Fucose||Inhibitory Carbohydrate:|L-Fucose||Divalent Ions:|Ca++, Mn++, Zn++||Storage and Stability:|Lyophilized powder may be stored at -20°C.
