Streptavidin（Cat No.:I044225）is a tetrameric protein derived from Streptomyces avidinii that exhibits an exceptionally high affinity for biotin (vitamin B7), with a dissociation constant (Kd) in the femtomolar range. This strong non-covalent interaction makes streptavidin an essential tool in molecular biology, diagnostics, and biochemistry. It is commonly used in applications such as Western blotting, ELISA, flow cytometry, and affinity purification. Streptavidin’s lack of glycosylation, compared to avidin, reduces nonspecific binding, enhancing assay sensitivity. It is often conjugated to enzymes, fluorophores, or nanoparticles for targeted detection and molecular labeling.
