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). 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.

When your required O.D. value for the culture is IPTG Dissolve 1.2g IPTG (isopropyl-β-d-thiogalactopyranoside) in deionized water to a final volume of 50ml. 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.

The final concentration of IPTG in indicator plates should be 0.2 mM.

This protocol describes the preparation of a 5-bromo-4-chloro-3-indolyl β-D-galactopyranoside (X-gal) stock solution at various concentrations.. Typically used in conjunction with IPTG for blue/white screening via the lac operon. A typical stock concentration of X-gal is 50mM (20mg/mL).To apply X-gal directly to the top of agar plates for blue/white screening, apply 40μL and wait to dry.

Note: To prepare 10 mL 1M IPTG stock solution, weight 2.38 g IPTG and dissolve in 8 ml distilled water, adjust to a final volume of 10 ml with distilled water. A stock solution (0.1 M) is prepared by dissolving IPTG in water with subsequent sterile filtration of the solution. The final concentration of IPTG in indicator plates should be 0.2 mM.

Thermo Scientific IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose. 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).
