Streptavidin (PE Conjugate)#36777,Cell Signaling Technology (CST),36777

Streptavidin has a remarkably high affinity for its natural ligand, biotin. The complex and irregular structure of the biotin-binding site makes it highly optimized for biotin binding and confers great specificity to the streptavidin-biotin complexes (4).

Reactivity

Source / PurificationStreptavidin is a protein that is derived from the bacteriaStreptomyces avidinii. Streptavidin (PE Conjugate) is purified by SEC-HPLC.

Scientific Background

Streptavidin is a 53 kDa homotetramer isolated fromStreptomyces avidiniifor use in isolation and detection bioassays (3). Each streptavidin subunit forms high affinity non-covalent bonds with the vitamin biotin. Because of its strong non-covalent interaction with biotin, streptavidin can be used to isolate and detect biotinylated proteins (1,2).Updyke, T.V. and Nicolson, G.L.
