Eterneon™ dyes represent a new generation of fluorescent dyes.

They feature a low molecular weight and good solubility in a wide range of solvents, which makes them ideal for life science applications. Further advantages comprise:

  • extremely high photostability
  • coverage of almost the entire visible spectrum
  • large stoke shifts (up to 180 nm)
  • pH independence
  • no cytotoxicity
  • available as NHS Esters and as Azides
  • outstanding prices
