Description

  • Highly hydrophilic, viscosity-sensitive, thiol-reactive label containing one maleimide group.

 

Applications

  • Covalent labeling of proteins, thiol-modified DNA and thiol-modified oligonucleotides
  • Viscosity sensitive label for probe environment
  • Viscosity sensitive fluorescence lifetime label — this label exhibits a distinct lifetime change upon changing the viscosity of the environment

 

Advantages

  • Perfectly suited for excitation with the 330, 436, and 470-nm diode lasers and UV light
  • Large Stokes' shift
  • Viscosity related changes in Q.Y. and lifetime
  • pH-insensitive between pH 3 and pH 10 
  • Good aqueous solubility
  • Ideal for non-radioactive labeling of proteins, thiol-modified DNA probes and thiol-modified oligonucleotides
