Description

Fluorescent Dye Eu with Streptavidin conjugate

Fluorescent Dye Eu is optimized for TR-FRET applications with large Stokes shifts and extremely long emission half-lives when compared to traditional fluorophores such as Alexa Fluor™ or Cyanine dyes. Ideal for labeling via Streptavidin for fluorescence imaging and other fluorescence-based biochemical analysis. For most fluorescent streptavidin applications, a concentration of 1 to 20g/mL is sufficient. The optimal working dilution should be determined by the end user.

• Typical Acceptor for TR-FRET: Alexa 647, APC, Cy5, DyLight 650, Fluorescence Dye 647-I, TF5
• Molar Extinction Co-efficient: ≥22,000 M^-1cm^-1
• Excitation (Max): 346nm
• Emission (Max): 617nm
• Solubility: Water
• Storage Buffer: Water

Application: Conjugation, Time Resolved-Fluorescence Resonance Energy Transfer

Recommended Storage: Store in desiccated environment at -20°C and avoid from light.
