We are looking for a nucleic acid stain that can show chromatin banding, but does not fall into the DAPI and Hoechst wavelength. We need to observe chromatin banding on a SIM super resolution. However, this scope didn’t come with a DAPI laser when purchased. Does anyone know any way to overcome this? I called Thermo Fisher to recommend some of their green nucleic acid dyes, but they do not know any that has been tested for chromatin banding.
