Biotinylated Anti-Streptavidin Antibody

Cat. No: BA-0500
Price: $151.00
Unit Size: 0.5 mg


Biotinylated Anti-Streptavidin has been widely used as an amplifying reagent in immunohistochemistry, in situ hybridization, microarray assays, ELISAs, blots, and many other applications. The capability of binding streptavidin via either biotin binding sites or through antigen binding sites, makes this biotinylated antibody unique.   Our antibodies to streptavidin are produced in goats using our highly purified streptavidin and isolated by affinity chromatography. Anti-Streptavidin does not bind avidin and Anti-Avidin does not recognize streptavidin. These antibodies provide opportunities to significantly amplify signals in many applications.

More Information

These antibodies can be used either as part of preformed complexes or in sequence to amplify fluorescent signals. When used in sequence, the target is first labeled with fluorochrome-conjugated avidin or streptavidin, followed by incubation with Biotinylated Anti-Avidin or Biotinylated Anti-Streptavidin, followed by a second layer of fluorochrome-conjugated avidin or streptavidin. This sequence can be repeated. This multi-layered approach introduces more fluorochromes at the target site and can provide a multi-fold amplification over a single layer.

These affinity purified antibodies are also available unconjugated or fluorescein-labeled.

The following figures illustrate different experimental setups used to achieve increasing levels of sensitivity.
