我们的AviTag™技术是利用大肠杆菌的生物素连接酶(BIRA)，在一个15个氨基酸肽标记上，对单一生物素进行高度靶向的酶结合。AviTag™序列为GLNDIFEAKIEWHE。定向在链霉亲和素涂层表面，这创造了一个理想的表现分子结合相互作用。

Avidity develops and sells molecular affinity tools for connecting molecules. Our patented AviTag™ technology employs a highly targeted enzymatic conjugation of a single biotin on a unique 15 amino acid peptide tag using the biotin ligase (BirA) from E. coli. AviTag™ sequence is GLNDIFEAQKIEWHE. Oriented on streptavidin-coated surfaces, this creates an ideal presentation for molecular binding interactions.

The scientific benefits of Avidity's AviTag Technology have garnered notice. Currently, AviTag technology is licensed by seven of the world's top ten pharmaceutical companies and is used by researchers in 22 countries.
