1. Prepare a 1M stock of IPTG (using the Molarity formula) and store at -20 degress centrigrade and away from light ( IPTG is light-sensitive). 2. When your required O.D. value for the culture is

This video provides a protocol for a 1M IPTG stock solution, and provide some tips for long term storage! Check it out! http://goo.gl/ZeLeA.

IPTG is used to induce expression of cloned genes under control of the lac operon (see Reference 1). 2011-12-23 Dilute your 50 mg/mL stock 1:500 into growth media to obtain the usual 100 µg/mL antibiotic restriction. IPTG (1M) Dissolve 2.83 g IPTG in 8 mL dH2O. Bring to 10 mL with additional dH2O.

IPTG is used to induce expression … Product Description. 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. You can prepare a stock solution of 0.5M IPTG and use 1ul for each ml. Meaning if your sample is 100 ml, you can use 100 ul from your stock.

Isopropyl β-d-1-thiogalactopyranoside (IPTG) 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 protein expression where the gene is under the control of the lac operator

The final concentration of IPTG is 0.1M.
