Figure 4From: Rapid identification and mapping of insertion sequences in Escherichia coli genomes using vectorette PCRPCR amplification of IS2 flanking DNA from genomic DNA digested with Bst UI. Flanking DNA fragments IS2-3A and IS2-6A (left hand side) and IS2-2B (right hand side), masked by other amplified fragments when genomic DNA was digested with Rsa I (see Fig. 2), were recovered with Bst UI.Back to article page
