Before revision:  We measure the fold-change in gene expression at different inducer concentrations in a collection of strains that span a  range of repressor copy numbers and operator binding strengths . After inferring the inducer dissociation constants using data from one of these strains, we show the broad reach of the model by predicting the induction profiles of all other strains  .
