For isolating biotinylated molecules and complexes with biotinylated components, including antibodies, antibody-antigen complexes, ligands and receptors, nucleic acids, and nucleic acid-protein complexes
Streptavidin is provided in lyophilized form in 10 mM phosphate buffered saline, pH 7.4. Reconstitute with 1 ml of distilled or deionized water. Store at 4°C.
Commonly used in indirect staining protocols to detect biotinylated primary antibodies in flow cytometry. Streptavidin binds to biotin with high affinity.
