Description

SeTau 647-DBCO (K9-4154) is an extremely bright, hydrophilic click chemistry reagent containing one dibenzylcyclooctyne (DBCO) group for strain-mediated cycloaddition reactions with azides. It has the same excitation wavelength as Cy5, Alexa Fluor™ 647 and can therefore be used with these filter sets. Its emission is at 690 nm.

 

Applications

Strain-mediated click chemistry reactions with azide-modified reagents and biomolecules.

 

Advantages

  • Suited for excitation with the 647 nm Kr-laser or 650 nm diode laser
  • pH-insensitive between pH 3 and pH 10 
  • Good aqueous solubility
  • Extremely bright label: SeTau 647: (Φ = 0.60, ε = 200,000 and Φ. ε =120,000) vs Alexa 647: (Φ = 0.33, ε = 270,000 and Φ. ε = 89,100)
  • Very high photostability; e.g. compared to fluorescein, Cy5 or Alexa 647
