Streptavidin is a biotin-binding protein purified from Streptomyces avidinii with a near neutral isoelectric point.Streptavidin is composed of 4 identical polypeptide chain subunits, which binds 4 moles of biotin per mole of protein with a high affinity (K_d ~10^-15).ProteoChem"s high purity streptavidin has a specific activity >14.0 U/mg of protein and is predominantly a single band by SDS-PAGE. Streptavidin is lyophilized and may be reconstituted with water.Biotinylate your protein or antibody of interest using ProteoChem"s Biotinylation Reagents for use in conjunction with streptavidin.Molecular Weight: ~52,000 daltonsCAS Number: 9013-20-1
