Students add 275 microliters of the IPTG stock to the 22 ml culture remaining. students should use their previously made lysozyme stock solution (the one you
The stock solution of IPTG is stable at this temperature for 2–4 months. We generally solve this by inducing at lower concentration of IPTG at 16 degrees overnight. You can make 1M concentarion stock of IPTG and add the volume accordingly as you want and as per your IPTG stock solution. (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) 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 2011-12-23 Stock solutions in anhydrous DMSO can be stored desiccated at -20°C for one month or longer. Esters should be diluted in aqueous solution immediately before use.

Dry opened LB plates at room temperature under UV light for about 30 minutes. This protocol is for the Preparation of X-Gal/IPTG LB Agar Plates for Blue/White Colony Screening. 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. or buy 25 mL 1M stock solution Teknova 13431 (Fisher) Store at -20C Prepare 100mM IPTG solution in dH 2 O (or dilute from 1M IPTG Stock Solution). Agar Media (Recommended) 1.
The final concentration of IPTG in indicator plates should be 0.2 mM. 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.
This video provides a protocol for a 1M IPTG stock solution, and provide some tips for long term storage! Check it out! http://goo.gl/ZeLeA.
Directions: 1) Mix 238 mg of IPTG with 900 µl of ddH 2 O.. 2) Add ddH 2 O until final volume is 1 ml.. 3) Store at -20°C.

Succinimidyl esters (SE) should be dissolved in a solution that is free of amine-containing compounds like Tris, glycine, or protein, which will react with the SE functional group. 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.

Stock IPTG (200mg/ml or 0.8M). Dissolve 2 grams of IPTG in 8 Prepare 800 mL of distilled water in a suitable container. · Add 200 g of IPTG to the solution.
IPTG (stock solution, 200mg/ml) IPTG is isopropylthio-D-galactoside. Make stock solution of IPTG by dissolving 1 g of IPTG in 4 ml of distilled H 2 O. Adjust the volume of the solution to 5 ml with H2O and sterilize by passing it through a 0.22-µm disposable filter. Dispense the solution into 1-ml aliquots and store them at -20°C.
Sterilize by passing through a 0.2 µm filter. Freeze at -20 °C. Induction of protein expression is usiually accomplished with an IPTG concentration of 0.5-1 mM. The following information for IPTG is provided by Sigma-Aldrich: The IPTG solutions may be aliquoted and stored at -20°C. IPTG solutions can be stored at room temperature for up to one month. solutions and a mask when weighing the powder.
