WebDescription. Streptavidin binds to biotin with high affinity. Streptavidin-HRP is useful for detecting biotinylated antibodies, e.g., in ELISA, ELISPOT, IHC or Western blotting.For ELISA applications, HRP will act on soluble substrates, such as ABTS or TMB, to yield a colorimetric reaction. WebStreptavidin and its homologs (together referred to as streptavidin) are widely used in molecular science owing to their highly selective and stable interaction with biotin. Other …
