tetR-Ptet-GFP(STm codon harmonized)

We have cloned our Salmonella codon harmonized GFP (BBa_K3861019) to a tetracycline-controlled transcriptional activation system (pTet-tetR, BBa_K3861011 ). The tetR system is well characterized and may be the most used gene expression controlling promoter system to date.1 There are two variants of this promoter-induction system, called Tet-On and Tet-Off.2,3 We use the Tet-On variant that selectively activates expression in the presence of tetracyclines. Important for our needs is the fact that tetracycline (or Anhydro-tetracycline) can passively penetrate bacterial membranes and no active transportes systems is crucial for this inducible expression system.
