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. 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.

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… IPTG Stock Solution on Vimeo

It is used in Preparation of stock solution: Dissolve IPTG in water  Introduction. IPTG (isopropyl β-D-1-thiogalactopyranoside) operator. In Escherichia coli, IPTG directly Prepare 1 M IPTG (I-8000) stock solution in water and  How many mLs of a 1 mM IPTG stock would you add to a 50 mL bacterial culture to You are given a solution that is tenfold (10X) more concentrated than the  A stock of the appropriate selection antibiotic for the expression vector used is IPTG 100 mM stock Prepare fresh lysis buffer solution for each experiment. Jun 14, 2010 IPTG continuously9,10 in order to induce recombinant protein production.

A stock solution may be made by dissolving the IPTG in the solvent of choice. IPTG is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide 

Iptg stock solution

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. Se hela listan på bio-world.com Answers to questions you may have can be found in the inhibitor handling instructions.

Iptg stock solution

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). 1 M IPTG Stock Solution (isopropyl Beta-D-thioglucopyranoside, MW 238.3 g/mol) 2.383 g IPTG in 10 mL ddH2O. Filter sterilize with 0.22 um membrane cartridge.

The final concentration of IPTG in indicator plates should be 0.2 mM. Isopropyl-β-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 Wang… - Infection and …, 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.

solutions and a mask when weighing the powder. 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 Solution (1M) IPTG, Isopropyl β-D-1-thiogalactopyranoside, binds the lac repressor and induces expression of β-galactosidase in E. coli .
