Design Notes

The circuit is under the regulation of the pLAC promoter. When inserted in a high copy number plasmid pLAC behaves as a constitutive promoter and hence does not require IPTG induction. However, if inserted in a low copy number plasmid, the system will have to be induced with IPTG as it would then behave like an inducible promoter. GFP, in this case, will be produced only in the presence of IPTG and at pH is 8.5
