Molecular Probes™ Streptavidin, Alexa Fluor™ 790 Conjugate

Description

• 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 fluorescence High solubility in aqueous solutions Available in multiple colors Ideal for western blots Properties of Alexa Fluor™ Dyes Alexa 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 Biotin Naturally 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
