Description

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

 

Applications

  • Covalent labeling of proteins, peptides, amino-modified DNA, amino-modified oligonucleotides and lipids.
  • Fluorescence lifetime assays.
  • Measurement of high-molecular-weight antigens in Fluorescence Polarization Immunoassays.

 

Advantages

  • Strongly fluorescent label for proteins and other biomolecules
  • Long fluorescence lifetime of 26.2 ns in water
  • Perfectly suited for excitation with the 380-nm, 404-nm and 436-nm diode lasers or the new 330-nm LED.
  • Large Stokes' shift (> 100nm)
  • Highly soluble in aqueous buffer
