This special yellow-emitting fluorescent dye exhibits advanced click reaction kinetics. Therefore, also less amount of copper can be used in the reaction mixture without any effect on the great reaction efficiency. This effect can be crucial e.g. when copper sensitive enzyme or biomolecules shall be labeled. Once attached to a biomolecule fluorescence microscopy detection can be carried out just like with Cy3, or any other alternative dye.

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.
