One point that has not yet been mentioned:
What will happen to the cells transformed with the plasmid if there is
no longer an amp resistance on it? If you adjust your growth conditions
so that the cells still can grow, will the cells keep a high copy number
of your plasmid? What results will that have for your expression level?
