- 60 kDa non-glycosylated protein composed of four identical subunits, each of which has a binding site for biotin
- Purified from Streptomyces avidinii
- Resembles egg white avidin in its biotin binding properties
- In most applications streptavidin and avidin are interchangeable

Our streptavidin is isolated from Streptomyces avidinii by a specific affinity system which results in a homogeneous, ultrapure streptavidin with very low nonspecific binding characteristics. Unconjugated streptavidin is recommended for use in solid-phase assays and immunohistochemical applications when the technique of sequential addition of reagents ( sandwich technique ) is employed. This reagent has also been effectively employed in subtractive hybridization procedures.
