Product Description
Streptavidin is a tetrameric protein composed of identical subunits. Each subunit binds one biotin molecule with an extremely high affinity (KD ~1x10⁻¹⁵ M). This preparation contains a core streptavidin variant, which is an N- and C-terminal truncated form with improved properties, including:
Enhanced homogeneity
Increased solubility
Greater resistance to proteolytic degradation
Improved accessibility of the biotin-binding pocket
Compared to native streptavidin, the core streptavidin variant offers superior performance in various applications. The high-affinity binding of streptavidin to biotin and biotinylated molecules has made it a critical component in diagnostics and laboratory kits.
