Alexa Fluor™ 790 streptavidin comprises 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). Alexa Fluor™ dye streptavidin conjugates are supplied as 1 mg lyophilized product or in 0.5 mL volumes of a 2 mg/mL solution.Important Features of Alexa Fluor™ 790 Streptavidin Conjugates:Alexa Fluor™ 790 streptavidin conjugate has Ex/Em maxima of ∼(782/805)Bright, photostable fluorescenceHigh solubility in aqueous solutionsAvailable in multiple colorsIdeal for western blotsProperties of Alexa Fluor™ DyesAlexa Fluor™ dyes are organic fluorescent dyes developed for better performance in imaging and other labeling protocols and exhibit improved photostability and brightness and improved solubility in aqueous solutions. Available in a broad range of colors, these dyes are a good choice for most imaging applications.Blocking Endogenous BiotinNaturally occurring biotins can interfere with biotin-streptavidin detection schemes.
