Dear All,
We are looking for a commercially available nuclear dye for fixed cells (tissue sections) in the near-IR portion of the spectrum that would be easily separated from Alexa-647, e.g with the excitation maxima in the 690-750 nm range?Any advice would be greatly appreciated.
Many thanks in advance.
