Description

Streptavidin, Alexa Fluor™ 790 Conjugate

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.
