Mapping of the Tn599 insertions. (a) PFGE image of a set of clones (lanes 2–16) carrying the transposon, after digestion with PI-SceI. (b) Corresponding Southern blot hybridized with labeled probe. Data from (a) and (b) together allows the correct mapping of the transposon in each clone. Lanes 1 and 17 corresponds to Low Range PFGE Marker (NEB) and Lane 18 is Mid Range I PFGE Marker (NEB). Run conditions were 6 V/cm, 14°C for 20 h and a pulse time ramp of 0.4–10 s.
