Figure 5From: Isolation and characterization of Ehrlichia chaffeensis RNA polymerase and its use in evaluating p28 outer membrane protein gene promotersIn vitro transcription showing the effect of varying salt concentrations of potassium acetate (Panel A), and sodium chloride (panel B). Transcription of the p28-Omp19 promoter region in pRG198 plasmid was assessed using the purified E. chaffeensis RNAP.Back to article page
