Fig. 3From: Implementation of the agmatine-controlled expression system for inducible gene expression in Lactococcus lactis Sensitivity of the ACE system to agmatine. Strength of induction of gfp in L. lactis NZ9000 pACE-GFP. GFP protein activity was determined under a range of agmatine concentrations. Data represent the average of three independent experiments. Bars indicate standard deviations (*p < 0.05)Back to article page
