异丙基-β-D-硫代半乳糖苷/异丙基-β-D-硫代半乳糖吡喃糖苷/IPTG/Isopropyl-β-

 Description
Application IPTG is commonly used in cloning procedures that require induction of β-galactosidase activity. It is used in conjunction with X-Gal or Bluo-Gal in blue-white selection of recombinant bacterial colonies that induce expression of the lac operon in Escherichia coli. IPTG functions by binding to the lacI repressor and altering its conformation, which prevents the repression of the β-galactosidase coding gene lacZ.
Other Notes Non-metabolizable galactose analog.
Reconstitution A stock solution （0.1 M） is prepared by dissolving IPTG in water with subsequent sterile filtration of the solution. The final concentration of IPTG in indicator plates should be 0.2 mM.
