Copy number comparison of plasmid with and without the ParABC partitioning system

Plasmid	Fraction of cells with plasmid	Plasmid/oriC in total population of cells	Plasmid/oriC per* plasmid-containing cell
pXX704 (sopABC)	0.89	0.47	0.52
pXX705 (ΔsopABC)	0.29	0.16	0.56
pXX762 (soj, spo0J-parS)	0.78	0.38	0.49
pXX764 (parS)	0.50	0.27	0.55

^*The plasmid/oriC ratio was divided by the fraction of cells containing a plasmid.
