Useful:

• Uses: Streptavidin from Streptomyces avidinii has been used-for blocking of the AFM (atomic force microscopy) tip, during the measurement of unbinding forces in the avidin-biotin systemfor coupling of anti-HA (hemagglutinin) antibodies during cell free synthesis and assembly of proteins on a biochipfor the coating of the gelatin flow phantoms to eventually determine the feasibility of IVUS (intravascular ultrasound) transducer for (biotinylated) microbubble-based drug deliveryto immobilize proteins and oligonucleotides Applications for enzyme-labeled (HRP, AP) streptavidin: Enzyme immunoassays (EIA), including enzyme-linked immunsorbent assays (ELISA) with biotinylated antibodies Cell and tissue staining (for light microscopy) Western blotting (WB) and other membrane-based biotin detection Applications for fluorescent (FITC, TRITC or Texas Red* Fluor-labeled) streptavidin: Immunofluorescent assays (IFA) Tissue staining (for fluorescence microscopy) Blot immunostaining Cell staining (incl. fluorescent activated cell sorting) Streptavidin is used as a tetrameric protein used to visualize biotin conjugated molecules in ELISA. Due to the strong affinity of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits. Streptavidin is widely used in molecular biology through its unique high affinity for the biotin.
