Detailní popis

Thermo Scientific IPTG (isopropyl-beta-D-thiogalactopyranoside) is a  highly stable synthetic analog of lactose. It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under control of the lac operon (see Reference 1). It is used in conjunction with X-Gal (#R0941) to determine the lac phenotype in blue/white colony screening.


  • Blue/white colony screening to distinguish recombinant (white) from non-recombinant (blue) colonies (see Reference 1)
  • Induction of gene expression under control of the lac promoter
