  • Eterneon-Red 645 Azide is a red fluorescent dye wich spectral properties just as Cy5. Due to its chemical structure though it is water-soluble and this very well suited for click conjugation with terminal-alkynylated biomoledules in aqueous media.

    FAQ

    • 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.
