Follow the same protocol for high copy, increasing the volumes of 
culture ans solutions. Try a purification step at the end as CsCl 
centrifugation or PEG precipitation, because the DNA will be dirtier 
and more contaminated with chromosomal DNA (just because you end up 
with more of everything...)
