WebStreptavidin (SA) is a biotin-binding protein isolated from Streptomyces avidinii, and is similar in size and affinity for biotin. In contrast to avidin, though, streptavidin is not glycosylated, which makes the protein less prone to nonspecific binding in IHC applications. Monovalent vs. monomeric Streptavidin is a tetramer and each subunit binds biotin with equal affinity. Multivalency is an advantage in applications like MHC tetramer staining, where avidity effects improve the ability of MHC molecules attached to streptavidin to detect specific T cells.
