FIG. 4.
PCR products (10 μl) amplified from recombinant plasmid pM8-2 (lane 1) and from chromosomal DNA from M. arthritidis H606 (lane 2) and M. arthritidis PG6 (lane 3) by using primers NT and HMPR were electrophoresed on a 1.5% (wt/vol) agarose gel and stained with ethidium bromide. PCR products differed in size in approximately 260-bp increments. Size markers are shown in lane M.
