Fig. 2From: Transcriptionally promiscuous “blurry” promoters in Tc1/mariner transposons allow transcription in distantly related genomesPromoter analysis in HeLa cells. Relative promoter activity, expressed as corrected mean RLU values, relative to the positive control (SV40 promoter, set to 100) and to the promoter-less construct (set to 0). Promoters with activity significantly different from the promoter-less reporter cassette are marked with an asterisk. Actual values of each experiment set are shown in Additional file 5: Figure S1Back to article page
