Figure 1From: Repressible promoters – A novel tool to generate conditional mutants in Pichia pastorisRegulation of different repressible promoters in liquid culture. Relative eGFP fluorescence per cell size under non-repressing (black) and repressing (gray) conditions using the promoters P SER1 , P MET3 , P THR1 , P PIS1 and P THI11 with different supplements. The relative standard deviation of eGFP fluorescence between replicates was between 10 and 20%.Back to article page
