Triplicate samples were placed in a 96 well microtitre plate and incubated at 37°C in a Tecan Genios Pro. Panel A: fluorescence (solid symbols, Relative Fluorescence Units; RFU) and absorbance (open symbols) were measured at 10 min intervals. Plasmids used were pSB3004 (□, ■; 4 sites), pSB3002 (□, ▲; 2 sites) and pSB3000 (○, ●; no sites). Panel B. luminescence (solid symbols, Relative Light Units; RLU)) and absorbance (open symbols) were measured at 10 min intervals. Plasmids used were pSB3014 (□, ■; 4 sites), pSB3012 (△, ▲; 2 sites) and pSB3010 (○, ●; no sites). Data is presented as % maximal signal to allow direct comparison of expression kinetics despite the fact that light levels from each construct were different.
