Vector Labs 公司是世界著名的生物学检测试剂公司，七十年代其在全球首推的生物素-亲和素系统引领了生物学检测方法的重大革命，该系统被普遍视为目前最灵敏、最可靠与最有效的染色系统，并被广泛应用于免疫组织化学、免疫电镜、原位杂交与凝集素化学中。该系统仍在不断地发展，以满足广大研究人员的各种不同要求。Vector 公司还是世界上凝集素产品的主要供应商，并提供大量的新产品，如酶底物、神经元示踪剂及蛋白质、糖类与核酸的标记、分离与检测试剂。
Vicia Villosa Lectin (VVL, VVA), Fluorescein
Description
VVL recognizes preferentially α- or β-linked terminal N-acetylgalactosamine, especially a single α-N-acetylgalactosamine residue linked to serine or threonine in a polypeptide (the Tn antigen). Evidence suggests that this lectin also may require specific amino acid sequences at the receptor site of glycosylation. The disaccharide galactosyl (α-1,3) N-acetylgalactosamine is also a potent inhibitor of this lectin.
Fluorescein labeled Vicia villosa lectin has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated fluorochromes. The excitation maximum is at 495 nm and the emission maximum is at 515 nm.
