Streptavidin is widely used in molecular biology through its unique high affinity for the vitamin biotin. The dissociation constant (Kd) of the biotin-streptavidin complex is about ~10-15 mol\/L. The strong affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits. The streptavidin\/biotin system has one of the biggest free energies of association of yet observed for noncovalent binding of a protein and small ligand in aqueous solution (K_assoc = 10**14). The complexes are also extremely stable over a wide range of temperature and pH.\u003c\/p\u003e\n\u003ch3\u003eProduct format\u003c\/h3\u003e\n\u003cp\u003eProvided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development.
