Description

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

 

Applications

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

 

Advantages

  • Highly 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
