stain genomic and plasmid DNA - FACS analysis (Jan/04/2007 )

I'm searching for dyes for FACS analysis that only stain genomic and plasmid DNA specifically. This means i'm looking for one dye that only stains genomic and another dye that only stains plasmid DNA, to calculate the ratio between genomic and pDNA online.
Does anybody knows something about such dyes?
Many thanks in advance!


I'm pretty sure there isn't one. You might be able to label plasmids with a sequence specific probe if you knew the plasmid sequence, but DNA is DNA.
