Dear all,

does anyone of you know of a plasmid (for E coli or Bacillus) that 
exists only as one copy in the cell??
I just found the pEU720 (described in Froehlich and Scott, Gene 108 
(1991), 99-101) and the F-plasmid.
Both are rather big, 13kb and larger. For the F-plasmid I found that 
there exist so called mini-Fs buit they exists in copynumber of 5-10.

So any comment is highly appreciated.

cheers, Holger
