Background
Streptavidin is a a homo-tetrameric protein produced by Streptomyces avidinii with strong biotin-binding ability. The non-covalent, yet strong bond between these two molecules has made it a preferable option in biological detection systems. This tetrameric protein has four binding sites for biotin. The strong bond between streptavidin and biotin has turned this complex into a practical immunological tool used in western blotting, enzyme-linked immunosorbant assays (ELISA), and immunohistochemistry. The streptavidin-biotin system is most used in the purification and identification of biological molecules. This system can also be used to attach various biological molecules to each other and to solid surfaces. 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.
