T7 RNAP + IPTG->PoPs (Mutant I)
This is a mutant T7 promoter that includes a lacO sequence. This is repressible by the LacI protein and is induced in the presence of IPTG. The promoter sits in the 5' region of the gene of interest and initiates transcription when the cell expresses T7 RNA polymerase. Be sure you are using a cell strain that includes this gene (DE3).
