Isolation of plasmid DNA from transfected eukaryotic cells

Hello All!

I'd like some advice on which protocol to use to isolate episomal plasmid
DNA from mammalian cells which have been transfected via CaPO4
precipitation. Is there a method that will yield clean plasmid with a
minimum of chromosomal contamination? Is such a thing even possible? Or
does a good genomic DNA prep have enough plasmid in it to use in southerns
and PCR experiments?

Along the same lines, I'd like to know if anyone has used a good DNA
isolation protocol and PCR to detect either episomal or integrated plasmid
in tissues of animals.
