Fluorescence intensity of eGFP in E. coli JM109 expressed from the indicated plasmids. The cells were induced with 0.2% (w/v) L-rhamose and the fluorescence intensity was measured. Intensity after 2, 4, 6, 8 and 24 h are shown in (A) fluorescence per 0.01 OD600 and in (B) fluorescence per ml culture. Values shown are the averages of three independent experiments, for the measuring points at 24 h the standard deviation is indicated.
