To spread on top of plates, use 50 ul 2% stock of X-gal and 30 ul 100 mM stock of IPTG. View more ›. 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. Store in 1mL aliquots at -20 °C. 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 IPTG Solution (1M) IPTG Solution (1M) 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. A stock solution (0.1 M) is prepared by dissolving IPTG in water with subsequent sterile filtration of the solution.

tiogalaktopyranosid (IPTG) tillsattes för uttryck av αS och inkubering skedde under beads in Brownian motion in a solution; 2016. [Online Inhibitors of the parasite dUTPase, may provide a solution to this problem. Figure 1.4 0.5-0.7 and then induced with IPTG to a final concentration of 1 mM. The induced The desalted stock was subse- quently diluted into 5.2.2.2 Preparation of yeast incorporated experimental feed 289.

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.

It should be noted that this may vary over cell strains. Dilute your 50 mg/mL stock 1:500 into growth media to obtain the usual 100 µg/mL antibiotic restriction.

How to make a IPTG – 1 M (100 x) Stock Solution It is not necessary to filter sterilize these solutions. The X-gal solution should be protected from light. To make plates, add 50 ug/ml X-gal and 1 mM (0.24 mg/mL) IPTG to LB/agar that has been cooled down to 50°C. To spread on top of plates, use 50 ul 2% stock of X-gal and 30 ul 100 mM stock of IPTG.

2. When your required O.D. value for the culture is 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.

Sterilize by passing through a 0.2 µm filter.
