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. Expression of GST-UCHL3 in BL21 (DE3) cells was induced by the addition 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. 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.

Dry opened LB plates at room temperature under UV light for about 30 minutes. 3. Add 40 μL of the Thermo Scientific X-Gal Solution (20 mg/mL), ready-to-use (Cat # IPTG Induction and Extraction of Proteins from Bacteria. Prepared by Swathi Arur and Sudhir Nayak. 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.

Pour sterile warm LB agar (about 25 mL) into a Petri dish. 2. Dry opened LB plates at room temperature under UV light for about 30 minutes. 3.

adjust Volume to 1.0 ml. sterile filter and store at -20°C. (dilute 1:10000 for indicator agar plates, e.g. 100 µl IPTG stock per 1 L agar solution, dilute 1:1000 to soak nitrocellulose membranes for library screening) 2014-11-03 2013-02-28 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). 2011-12-23 Dilute your 50 mg/mL stock 1:500 into growth media to obtain the usual 100 µg/mL antibiotic restriction.
