2021-04-09 This protocol describes the preparation of a Isopropyl β-D-1-thiogalactopyranoside (IPTG) stock solution at various concentrations. A typical stock solution concentration is 100mM IPTG. A typical final concentration when using IPTG to induce protein expression under a lac operon is 0.1mM IPTG. IPTG Stock Quote.

Filter sterilize (0.2µm), and store in 5ml aliquots at –20°C. The final concentration of IPTG is 0.1M. The stock solution of IPTG is stable at this temperature for 2–4 months. IPTG is commonly used with X-Gal, Bluo-Gal and Magenta-Gal in molecular biology labs because of its ability to induce the lac operon without being metabolize Details. IPTG, Isopropyl β-D-1-thiogalactopyranoside, binds the lac repressor and induces expression of β-galactosidase in E. coli. IPTG is widely used to induce the expression of cloned genes under the control of the lac operon and to screen blue/white colony in X-gal plate.

Upon IPTG withdrawal (−IPTG), accumulation of the GFP-LacI protein on the lacO arrays occurs in a matter of hours. This system has been widely used to look at chromosomal domain dynamics (several megabases) with large amplified regions of lacO repeats or dynamics of smaller regions (~10 kb) using single 9) When the OD reaches 3-4, induce protein expression by adding IPTG. It usually takes approximately one additional hour for the OD to reach 3-4. IPTG: Weigh out 750mg IPTG and suspend in 9mL ddiH20. Vortex to get into solution. Pipette 3mL of this solution into each fermentation vessel.

It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under control of the lac operon (see Reference 1). 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.
