Streptavidin is widely used in Western blotting and immunoassays conjugated to some reporter molecule, such as horseradish peroxidase. Streptavidin has also been used in the developing field of Nanobiotechnology, the use of biological molecules such as proteins or lipids to create nanoscale devices/structures.
The Streptavidin-Binding Peptide (SBP)-Tag is a 38-amino acid sequence that may be engineered into recombinant proteins. Recombinant proteins containing the SBP-Tag bind to streptavidin and this property may be utilized in specific purification, detection or immobilization strategies.
Streptavidin is a tetrameric protein expressed in Streptomyces avidinii. Because of Streptavidin's high affinity for vitamin H , Streptavidin is commonly used in the fields of molecular biology and biotechnology. The Strep-tag was originally selected from a genetic library to specifically bind to a proteolytically truncated "core" version of ...
