Identification of chromosome fragments by PFGE. Plugs were prepared from stable Ura⁺ transformants derived from CFV/YBR235-tg. The panel on the left shows the gel stained with SYBR gold, the panel on the right is a Southern blot of the same gel probed with a PCR product derived from YBR235 to indicate chromosome II and the CF.
