Isopropyl β-d-1-thiogalactopyranoside (IPTG) is a molecular biology reagent. This compound is a molecular mimic of allolactose , a lactose metabolite that triggers transcription of the lac operon , and it is therefore used to induce protein expression where the gene is under the control of the lac operator .
IPTG is a reagent which mimics the structure of allolactose, and can therefore bind to the lac repressor and prevent it from inhibiting gene expression. Once enough IPTG is added, the T7 gene is normally transcribed and so transcription of the gene of interest downstream of the T7 promoter also begins. [6]
Each signal activates expression of a separate gene (shown in light blue). The expressed proteins then can either form a complete complex in cytosol , that is capable of activating expression of the output (shown), or can act separately to induce expression, such as separately removing an inhibiting protein and inducing activation of the ...
The lacUV5 promoter is a mutated promoter from the Escherichia coli lac operon which is used in molecular biology to drive gene expression on a plasmid. lacUV5 is very similar to the classical lac promoter, containing just 2 base pair mutations in the -10 hexamer region, compared to the lac promoter.

Isopropyl β-D-1-thiogalactopyranoside (IPTG), which functions as the inducer of the lac operon, may be used in the media to enhance the expression of LacZ. X-gal is an expensive material, thus other methods have been developed in order to screen bacteria. GFP has been developed as an alternative to help screen bacteria.
