Northern blot analysis of transgenic E. coli Top10F′ cells containing plasmids pBluescript, pBb:recA, and pBh:recA. Total RNA was separated on a 1% agarose gel with formaldehyde. The blots were probed with radiolabeled PCR products of the beta-lactamase (bla) gene of the plasmid (left) or a mixture of the recA genes of B. burgdorferi and B. hermsii (right). The positions of single-strand size markers (in nucleotides) are indicated on the left.
