Transcription anti-terminator test of UmRrm75. Anti-terminator assay of UmRrm75 in the RL211 E. coli strain. Cultures of RL211 (negative control), RL211-pINIII (negative control), RL211-CspA (positive control) and RL211-UmRrm75 bacterial strains were adjusted to OD600 1.0, and they were spotted in serial dilutions on LB plates with 8 or 10 µg/mL chloramphenicol. Plates were photographed after 48 h of incubation at 37 °C. Data shown are representative of three independent experiments.
