Thermo Fisher, S32356, Streptavidin, Alexa Fluor™ 594 Conjugate

Liquid, 0.
5 mL Alexa Fluor™ 594 streptavidincomprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor™ dye). Streptavidin has a very high binding affinity for biotin, and a conjugate of streptavidin is commonly used together with a conjugate of biotin for specific detection of a variety of proteins, protein motifs, nucleic acids, and other molecules (for example, a biotinylated primary antibody bound to a protein target can be detected with a fluorescently labeled streptavidin). Strategies similar to this are used in many detection protocols including western blots, flow cytometry, imaging and microscopy, and microplate assays. Alexa Fluor™ dye streptavidin conjugates are supplied as 1 mg lyophilized product or in 0.
5 mL volumes of a 2 mg/mL solution.
