Streptavidin-Sepharose Beads | 6565

Streptavidin, a protein from Streptomyces avidinii, is known to bind to biotin with very high affinity (dissociation constant 10-14 M). It has a tetrameric structure in which each molecule of Streptavidin binds to four molecules of biotin. These interactions have been utilized to isolate variety of biotin labeled proteins, antibodies and other biomolecules ( Cat #s 2322, 2323, 2326, 2345-2347). ’s leak-resistant Streptavidin conjugated beads are prepared by covalent conjugation of Streptavidin to highly cross-linked Sepharose beads by a proprietary method.
