Streptavidin /ˌstrɛpˈtævɪdɪn/ is a 52 kDa protein (tetramer) purified from the bacterium Streptomyces avidinii. Streptavidin homo-tetramers have an extraordinarily high affinity for biotin (also known as vitamin B7 or vitamin H). With a dissociation constant (Kd) on the order of ≈10 mol/L, the binding of biotin to streptavidin is one of the strongest non-covalent interactions known in natur… WebStreptavidin-conjugated magnetic beads and resins can be used to isolate proteins, cells, and DNA, or they can be used in immunoassays or bio-panning. Our family of biotin …
