I have a clone on a pUC-based vector in a male E. coli strain (has F'
plasmid) When I extracted the plasmid DNA from this strain, I got two high copy
number plasmids (one of them was supposed to be my clone). My questions are:
1. Is F'plasmid a high copy number in E. coli?
2. What is the size of the F' plasmid (its genotype is F' traD36 proAB<+>
3. How can I separate these two plasmids (can I separate them by transform
another E.coli strain, e.g. DH5a)?
Thanks a lot.
