Fig. 4From: Analysis of the leakage of gene repression by an artificial TetR-regulated promoter in cyanobacteriaSensorgrams of TetR interacting with promoters L09, L10, L11 and L12 in the absence (left) and presence (right) of [aTc∙Mg]+. TetR was injected in two-fold dilution series from 62 to 4 nM over immobilized promoters. The solid lines overlayed the experimental data (left) are theoretical best fit lines obtained by global non-linear regression analysisBack to article page
