Miranda:

I'm not an expert, but if you simply want to stain the DNA to see where it is, try one (or more) of the usual intercalating fluorescent stains (DAPI, maybe acridine) and use a fluorescence microscope.  ISH is certainly
an option, but that is a different investigation ("what DNA is it?" rather than "where is the DNA?" or "is there any DNA there?").

Tot siens,
Adrian Leek.
