IPTG, dioxan free 7757-83-7 They are cellulose based providingIPTG is an analog of galactose that is non metabolizable and inactivates the lac repressor to induce synthesis of galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. It is also 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 galactosidase and is most often used with
