    Growth Medium and Conditions

    The plasmid pACYC184 carries a gene encoding resistance to tetracycline (tet) and a gene encoding resistance to chloramphenicol (chloramphenicol acetyltransferase). To maintain the plasmid, cells should be grown with 25-50 µg/ml of tet and 35-50 µg/ml of cam. The plasmid, which is present at a low copy number, cannot be amplified using a standard chloramphenicol procedure but can be amplified using spectinomycin (50 µg/ml of growth media).
