Description

Purified recombinant streptavidin enables detection of biotinylated antibodies and other probes in a variety of standard assay methods including western blotting, ELISA, immunohistochemistry, and fluorescence imaging.

  • Purified streptavidin is supplied lyophilized in phosphate-based buffer for immediate reconstitution with water
  • Streptavidin is a biotin-binding protein originally isolated from Streptomyces avidinii
  • Pierce™ streptavidin products use a recombinant form of streptavidin having a mass of 53,000 daltons and a near-neutral pI
  • Streptavidin is a tetrameric protein, with each subunit binding one molecule of biotin with affinity similar to that of avidin
  • Guanidinium chloride will dissociate avidin and streptavidin into subunits, but streptavidin is more resistant to dissociation
  • Applications: ELISA (assay dependent), western blot (assay dependent)
