Product information "IPTG, dioxane free, Molbio Grade"

IPTG is commonly used in cloning procedures that require induction of β-galactosidase activity. It is used together with X-Gal > (5-bromo-4-chloro-3-indolyl-ß-D-galactoside) or Bluo-Gal > (5-Bromo-3-indolyl-beta-D-galactopyranoside) in blue-white selection of recombinant bacterial colonies that induce expression of the lac operon in Escherichia coli.

Mode of operation:
While IPTG binds to the lacI repressor it is altering the conformation of the lacl repressor, which prevents the repression of the β-galactosidase coding gene lacZ. Thus IPTG is an inducer of the lac operon in bacteria for detection of lac+ colonies.

Dissolve in water to e.g. 200mg/mL, sterilise by filtration and store in aliquots at -20°C. For detection of transformants, use in final concentration of 0.1mM up to 1mM in LB-Medium.
