FIG. 2.
Northern hybridization of total RNA from strain HB101 carrying different sfa plasmids and from strain 536. Either an sfaA-specific probe (A) or an sfaF-specific probe (B) was used. Lane 1, HB101/pJMT10; lane 2, HB101/pJMT9; lane 3, HB101/pJMT2; lane 4, HB101/pJMT8; lane 5, HB101/pJMT7; lane 6, HB101/pJMT6; lane 7, HB101/pJMT5; lane 8, HB101/pJMT4; lane 9, HB101/pJMT3; lane 10, 536; lane 11a, HB101/pANN801-13; lane 11b, overexposure of part of the blot in lane 11a in order to visualize the small amount of sfaBA and sfaADE transcripts detected. The positions of the different transcripts are indicated on the left and right.
