WebIPTG is an analog of galactose that is non-metabolizable and inactivates the lac repressor to induce synthesis of β-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. WebNov 20, 2024 · By adding 1 mM IPTG (Roth) (final concentration), recombinant protein expression was induced for 4 h at 28 °C with shaking at 180–200 rpm prior to harvest by centrifugation (5000g, 20 min, 4 °C). Cell pellets were frozen and stored at −20 °C until further processing. dust bags for bosch vacuum cleaners
