Induction in bacteria can be performed using one of two basic methods. Fast induction does not work for all proteins and can give you suboptimal yields. Slow induction can … IPTG Stock Stability & Storage. from ZellBio GmbH.

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. 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.
