The expression… IPTG Stock Solution on Vimeo 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. Isopropyl-Î²-D-thio-galactopyranoside (IPTG) stock solution (1.0 M): 4.8 g IPTG in 20 ml of sterile water Human {alpha}-Defensins Inhibit Hemolysis Mediated by Cholesterol-Dependent Cytolysins RI Lehrer, G Jung, P Ruchala, W Wangâ€¦ - Infection and â€¦, 2009 - Am Soc Microbiol Isopropyl-β-D-thiogalacto side (IPTG) is a chemical analog of galactose that cannot be cleaved by β-galactosidase. IPTG functions by binding to the lacI repressor and altering its conformation, which prevents the repression of the β-galactosidase coding gene lacZ. 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.

Here we have described the procedure to prepare 100 ml of 10 M sodium hydroxide (NaOH) solution. 40 g of NaOH is dissolved in ≈ 70 ml water. Since the dissolution process is exothermic, small quantities of NaOH are added to the water at a time instead of adding all 40 g in water. Once all NaOH is dissolved, the final volume of the solution is adjusted to 100 ml with water. IPTG, a non-metabolizable galactose analog, is commonly used in cloning procedures that require induction of β-galactosidase activity.

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. IPTG is an analog of galactose that is non-metabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli.

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. 100mM IPTG Solution is a high quality research product used as optimized stock solution of IPTG (isopropyl-beta-D-thiogalactopyranoside), a synthetic analog of lactose. IPTG inactivates the lac repressor of the lac operon, trigeering the induction of beta-galactosidase synthesis. Prepare a stock solution of IPTG at 0.1 M (23.8 mg/mL) in sterile distilled water and filter sterilize through a 0.22 micron disposable filter.
