WebBiotin and biotinylated substances bind to streptavidin, a molecule isolated from Streptomyces avidinii. The binding of streptavidin to biotin is one of the strongest … WebThe magnetic beads for separation of biotinylated biomolecules have a Streptavidin ligand. Streptavidin is an M r 60 000 protein from Streptomyces avidinii, and is a tetramer containing four biotin binding sites. Since the affinity between streptavidin and biotin is exceptionally high, harsh conditions are required for disruption, such as the use of SDS …
