Formulation Lyophilized powder from protein in buffered saline solution
Sufficient For Conjugation to sulfhydryl groups of approx. 1mg of antibody (150kDa) or molar equivalent
Description Pierce Streptavidin, Maleimide Activated
Quantity 1mg

These purified and conjugated forms of recombinant streptavidin protein enable detection of biotinylated antibodies and other probes in a variety of standard assay methods, including Western blotting, ELISA, immunohistochemistry and fluorescence imaging. Purified streptavidin and the streptavidin-HRP conjugates (peroxidase-conjugated streptavidin) are supplied lyophilized in phosphate-based buffers for immediate reconstitution with water. Alkaline Phosphatase conjugates are supplied as a liquid in a Tris-based buffer.


  • Recombinant streptavidin – high-quality protein, 53kDa, pI equals 6.8 to 7.5

  • Pure protein and enzyme conjugates – choose pure, unconjugated protein for biotin blocking and controls; enzyme conjugates for substrate-based detection

  • Fluorophore conjugates – standard fluorescent forms (fluorescein, rhodamine, etc.) for traditional immunofluorescence techniques

  • Activated preparations – choose a maleimide-activated or hydrazide-activated form to prepare a custom streptavidin conjugate with sulfhydryl- or carbohydrate-containing molecule
