Background: 

     Streptavidin is a tetrameric protein composed of identic subunits. Each  subunit binds one biotin molecule with a KD of ~1x10-15M. The preparation contains an  N- and C-terminal shortened variant (core streptavidin) with improved properties  concerning homogeneity, solubility, resistance towards proteolytic degradation and  accessibility of the biotin binding pocket as compared to native streptavidin. The high  affinity recognition of biotin and biotinylated molecules has made streptavidin one of the  most important components in diagnostics and laboratory kits.
