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.

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.

IPTG stock solution is typically made at a 1M concentration and stored at -20oC. We recommend making single-use aliquots to prevent repeated freeze-thaw cycles of IPTG in solution. IPTG is used in conjunction with X-Gal or Bluo-Gal in blue-white selection of recombinant bacterial colonies that induce expression of the lac operon in Escherichia coli.

A typical stock solution concentration is 100mM IPTG. A typical final concentration when using IPTG to induce protein expression under a lac operon is 0.1mM IPTG. For direct application to a solid media plate, add 56 μL of a 100mM IPTG stock solution directly to the plate top and allow to … Stock Solution Preparation of 1 M IPTG (1 M IPTG Recipe) Dissolve 2.38 g of IPTG in 8 mL of distilled H 2 O. Bring to a final volume of 10 mL with molecular biology grade H 2 O. Filter sterilize with a 0.22 μ syringe filter.

This protocol describes the preparation of a Isopropyl β-D-1-thiogalactopyranoside (IPTG) stock solution at various concentrations. A typical stock solution concentration is 100mM IPTG. A typical final concentration when using IPTG to induce protein expression under a lac operon is 0.1mM IPTG.

Vortex to get into solution. Pipette 3mL of this solution into each fermentation vessel. (The target final concentration of IPTG is approximately 300mM.) Make sure to return the IPTG to the -20ºC freezer. 10) Adjust Temperature. 1 M IPTG Stock Solution (isopropyl Beta-D-thioglucopyranoside, MW 238.3 g/mol) 2.383 g IPTG in 10 mL ddH2O.
