Description

  • Hydrophilic, amine-reactive, long-lifetime label containing one NHS-ester group, with one positive charge and chloride as the counter-ion.

 

Applications

  • Covalent labeling of proteins, amino-modified DNA, amino-modified oligonucleotides and lipids.
  • Fluorescence lifetime assays.
  • Fluorescence polarization-based assays of high molecular weight antigens.

 

Advantages

  • Highly fluorescent label for proteins and oligos.
  • High quantum yield (Q.Y.) ~ 80 % (water)
  • Long fluorescence lifetime of 9 ns in water
  • Perfectly suited for excitation with the 380-nm and 404-nm diode lasers
  • Large Stokes' shift of over 100 nm
  • High fundamental polarization R0 = 475 mP
  • Highly soluble in aqueous buffer (500 mg/L at 20°C)
