Figure 1From: Rapid identification and mapping of insertion sequences in Escherichia coli genomes using vectorette PCRVectorette PCR for amplification of IS franking sequences. The shadowed area represents the IS sequence. The solid lines indicate the flanking DNA sequences. ∇ indicates the restriction site. A and B are the outward IS-specific primers located at the ends of the IS. V is a vectorette primer.Back to article page
