I wanted to tag Eudragit S100 for the cellular uptake studies. As per some of the papers it is tagged with Rhodamin B or Nile Red (567/580nm). But I have a limitation for excitation laser. I can go with 375, 488 and 642 nm laser only. I can go with these dyes with very less excitation wavelength. But I want to go for some other dyes.
Plz do me favor...
