Fig. 2From: Study of in vitro transcriptional binding effects and noise using constitutive promoters combined with UP element sequences in Escherichia coli Mean gfp expression value driven by each UP element-promoter or promoter constructs in E. coli. The relative fluorescence unit (RFU) of gfp was normalized using the weakest promoter (J23109). Promoter was marked in black bar and UP element-promoter was marked in grey bar. Each constructs was tested at least with three replicatesBack to article page
