Product Name | Recombinant Streptomyces avidinii Streptavidin protein |
Description | Domain: 25-183aa. Recombinant His tagged streptavidin was expressed in E. coli and purified by using conventional chromatography techniques. MW: 17.5 kDa (167aa) confirmed by MALDI-TOF. Purity > 95% by SDS-PAGE. Streptavidin, a tetrameric protein secreted by Streptomyces avidinii, binds tightly to a small growth factor biotin. It finds wide use in molecular biology through its extraordinarily strong affinity for the vitamin biotin; the dissociation constant (Kd) of the biotin-streptavidin complex is on the order of ~10-15 mol/L. The high affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits |
