Isopropyl-beta-D-thiogalactopyranoside (IPTG) is a chemical analogue of galactose, which cannot be hydrolysed by the enzyme beta-Galactosidase. It induces the E. coli lac operon activity by binding and inhibiting the lac repressor without being degraded. Genes controlled by the lac or tac promoter/operator sequences are expressed to high levels in the presence of IPTG. Melting point: 112-113 °C.
