Pierce™ streptavidin
Fornitore: Thermo Fisher Scientific
Pierce™ Streptavidin is a purified unconjugated recombinant protein.
- Recombinant streptavidin high-quality protein
- Used for biotin blocking and controls
- Mostly used in ELISA (assay dependent) and western blot (assay dependent)
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 lyophilised in phosphate-based buffer for immediate reconstitution with water.
Streptavidin is a biotin-binding protein originally isolated from Streptomyces avidinii. In contrast to avidin, streptavidin has no carbohydrate and has a mildly acidic pI of 5. These products use a recombinant form of streptavidin having a mass of 53000 daltons and a near-neutral pI (6,8 - 7,5). 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.
