Dear Shan,
          this is a very interesting.  What is the aim of the proceedure?
To switch off chromosomal replication and allow plasmids to continue
replicating?  (I don't quite understand how this would help) or is this
completely empirical?  Do you have any results from the method yourself?

Regards, Mike.
