Isopropyl-β-d-thiogalactopyranoside (IPTG) is a kind of nonmetabolizable analog of lactose widely used for heterogeneous gene expression in Escherichia coli system. Lactose, a natural inducer of β-galactosidase gene, is the most popular substitute for IPTG due to its low cost and nontoxicity.
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.
