Wisteria Floribunda Lectin (WFA, WFL), Biotinylated

VVL prioritises the recognition of α- or β-linked terminal N-acetylgalactosamine, particularly individual α-n-acetylgalactosamine residues linked to serine or threonine in the polypeptide (Tn antigen). There is evidence that such lectins may also require specific amino acid sequences at glycosylated receptor sites. Disaccharide galactose (alpha-1,3) n-acetylgalactosamine is also a potent inhibitor of this lectin. Fluorescein-labeled corydalis lectins have the appropriate amount of fluorescent dye binding to provide the best staining properties for the lectins. This conjugated substance basically does not contain unconjugated fluorescent dyes. The excitation maximum is 495nm and the emission maximum is 515nm.
