WebIPTG is often used in the induction of recombinant proteins, is a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria. IPTG is commonly used in cloning procedures that require induction of β-galactosidase and is most often used with X-Gal for blue/white acterial colony screening. WebIPTG is an effective inducer of protein expression in the concentration range of 100 μmol/L to 3.0 mmol/L. Typically, a sterile, filtered 1 mol/L solution of IPTG is added 1:1000 to an …
