  • Probably the greatest advantage of this very special class of dyes is that they show quite outstanding spectral properties. Since absorption and emission wavelength are separated by a broad shift, they are optimal dyes for multiplexing with other dyes. One excitation wavelength can be used for instance to readout two dyes. Additionally, these dyes are ultra-photostable and mainly pH independent.


    • What are the Eterneon dyes?

      Our EterneonTM dyes are a special class of ultra-stable fluorescent dyes. Our long stokes-shift ones even have well separated peaks of absorbance and emission, so it is very convenient to characterize your sample with very sharp and strongly fluorescent signals. These special dyes are oligothiophene based, uncharged and not pH sensitive.
