Description: IPTG is the abbreviation for Isopropyl β-D-1-thiogalactopyranoside, a compound which induces the transcription of the gene coding for beta-galactosidase. It is used to induce protein expression where the gene is under the control of the lac operator. In blue-white screen, IPTG is used together with X-gal. Blue-white screen allows colonies that have been transformed with the recombinant plasmid rather than a non-recombinant one to be identified in cloning experiments.
