Dear scientists,
Which method do you recommend for the purification of a low copy plasmid that is larger then >150 kb from Enterobacteriaceae ?
The plasmid is a wild-type plasmid, so not specially designed for isolation out of an E. coli.

Greetings and already great thanks for your suggestions.

Armand.
