Avidity Avitag™ Technology
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.
