Thermo Scientific Pierce Streptavidin is a purified unconjugated recombinant protein form.

Features of Streptavidin:

Recombinant streptavidin—high-quality protein, 53kDa, pI = 6.8 to 7.5
Pure protein —choose pure, unconjugated protein for biotin blocking and controls

The 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 as lyophilized in phosphate-based buffers for immediate reconstitution with water.

Streptavidin is biotin-binding protein that was originally isolated from Streptomyces avidinii. In contrast to avidin, streptavidin has no carbohydrate and has a mildly acidic pI of 5. Thermo Scientific 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.

자주 묻는 질문(FAQ)

How many biotin binding-sites are there per streptavidin molecule?

Streptavidin is a protein composed of four identical subunits, each containing a high affinity binding site for biotin (K-D = 10 -15 M) . Streptavidin has the same biotin binding properties as avidin, but it has a low isoelectric point (pI=5) and no carbohydrate groups, resulting in low non-specific binding.
