Analysis of the genomic restriction pattern of different recipient clones upon transfer of PAI II₅₃₆ by PFGE. Genomic DNA of three representatives of the transconjugants carried either a chromosomally inserted PAI II₅₃₆ or an episomal circular intermediate (CI) were digested with SfiI. Donor strain 536 and recipient strain SY327λpir are controls. Recipients 26, 59, and 77 (marked with 'o') carried a PAI II₅₃₆-specific CI, whereas in strains 23, 46, and 54 PAI II₅₃₆ has been chromosomally inserted at the leuX tRNA locus.
