Background

Streptavidin is a bacterial protein (from Streptomyces avidinii) that has an exceptionally high binding affinity for biotin (B7). Streptavidin-biotin binding is one of the strongest known non-covalent interactions and is highly resistant to many conditions that would typically cause dissociation (such as organic solvents, denaturants, detergents, and extreme temperatures or pH). Streptavidin's affinity for biotin can be employed in a variety of experimental uses, from purifications to standards, to means of detection or pull down experiments.

Product Details

Streptavidin - S000-01
SA, S avidin, streptococcus avidin
15.5 U/mg by biotin titration method

Target Details

Streptavidin is chromatographically pure and shows predominantly a single 53,600 dalton band by SDS-PAGE.

Application Details

SDS-PAGE
IF, Microarray, Other, LFA  - View References
Streptavidin has been tested by SDS-PAGE and is suitable for use as antigen, as a control or standard in assays, and most other immunological methods as well as enzyme conjugates and complexes; Southern blots and other methodologies related to DNA and RNA analysis; Western blots; and purification of proteins or other antigens with biotinylated antibodies or lectins by use of immobilized streptavidin.
