Gel picture showing the electrophoretic separation of plasmids.

<p>The plasmids carried by ARD1257 (B), ARD1258 (C), and ARD1258C (D) migrating in 0.8% agarose, for 270 min at 150 v, 4°C, are shown. Lane A shows the reference plasmid bands from strain 39R861. The reference plasmid bands are from top to bottom; 148 kb, 63 kb, 36 kb, genomic DNA band, 6.8 kb. Lane A–C were run on a separate occasion to lane D but under identical run conditions with a reference plasmid.
