UEA I Lectin (FITC)

The anti-H (O) hemagglutinating activity of Ulex europaeus has been used widely to confirm blood group O activity. UEA I binds to many glycoproteins and glycolipids containing α –linked fucose residue. The purified lectin appears to be a dimer of two distinct polypeptide chains associated by noncovalent forces. This lectin does not react with Lea active blood group substance. The native protein has pI=6.-6.1 and exhibits a Molecular weight 6,-68, during gel filtration on Sephadex column. This lectin will hemagglutinate fresh blood group O cells at 2-5μg/ml.Inhibiting/Eluting sugars: 5-1 mM L-fucoseCarbohydrate-Binding Specificity of UEA I: L-Fuα1,2Galβ1,4GlcNAcβ1,6R
