Induce expression of amylase fusion enzyme by making culture 1 mM IPTG (500 ul of 1 M stock). Allow culture to express protein for 2 h – 4 h. 6. Remove cells by centrifugation (10,000 x g 10 min.) and retain supernatant. 7. Store media at 4 C until ready for protein purification. Section3:
IPTG Stock Solution. from ZellBio GmbH. 2 years ago. IPTG 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.

The expression… IPTG Stock Stability & Storage on Vimeo IPTG is a commonly used reagent in cloning procedures that require induction of β-galactosidase activity and is used in conjunction with X-Gal, Catalog Number B9146, or Bluo-Gal, Catalog Number B2904, in blue-white color selection of recombinant bacterial colonies. Preparation Instructions IPTG is soluble at 250 mg/ml in water and may be IPTG Induction Theory Isopropyl β-D-1-thiogalactopyranoside (IPTG, also known as lad-y) is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce E.coli protein expression where the gene is under the control of the lac operator. IPTG stocks should also be well kept. If possible, it can be useful to speak to your colleagues that use the same stocks as you to narrow down the problem (e.g. to check whether the stocks of IPTG is an analog of galactose that is non-metabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli.
