Streptavidin, Alexa Fluor 790 Conjugate, Streptavidin, Alexa Fluor 790 Conjugate, Each

Details:

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. For experiments involving fixed and permeabilized cells, try our endogenous biotin-blocking kit to minimize this interference.For research use only.
