I'm looking for a fluorescent dye for the single molecule experiment with DNA. The fluorescence dye will be labeled into a DNA. Since it is not for the FRET experiment, only the intensity and photostability of fluorescence are considered. Both Atto 532 and CF 532 dyes are said to be better compared to AF 532. However, I can't find the data they are comparing. Can you tell me which dye would be good in your experience?
