Streptavidin is a tetrameric protein derived from Streptomyces avidinii with an exceptionally high affinity for biotin (Kd ≈ 10⁻¹⁴ mol/L). This strong and specific interaction forms the basis for a wide range of biochemical and diagnostic applications, enabling the detection, purification, and immobilization of biotinylated molecules.
The Strep-tag system leverages this binding specificity by incorporating a short peptide tag into recombinant proteins, allowing for efficient purification and detection through streptavidin- or Strep-Tactin–based methods.
This polyclonal antibody specifically recognizes the Strep-tag epitope and is optimized for Western blotting, providing sensitive and reliable detection of Strep-tagged proteins in research workflows.
