Biotin streptavidin non specific binding
WebThe avidin-biotin interaction is widely employed as a universal tool in numerous biotechnological applications. In avidin-biotin technology, non-specific binding to biological macromolecules is a hindrance. The major origin of this non-specific binding is the electrical charge of the surface of biotin-binding proteins. WebStreptavidin / ˌ s t r ɛ p ˈ t æ v ɪ d ɪ n / is a 52 kDa protein (tetramer) purified from the bacterium Streptomyces avidinii.Streptavidin homo-tetramers have an extraordinarily …
