In vivo phosphorylation dynamics of the Bordetella pertussis

Culture plates with Amp can be stored at 4°C for about 2 weeks. Stock solutions can be stored at 4°C for 2 weeks but can last as long as 4-6 months when 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. This protocol describes the preparation of a 5-bromo-4-chloro-3-indolyl β-D-galactopyranoside (X-gal) stock solution at various concentrations.

Iptg stock solution

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.

Standard vials at three concentration Validation Study. Specificity. The apparent response at the levels; 0.1, 1, and 10 µM (n ) 5 at each concentration level) were retention time of IPTG was compared to the lower limit of injected for stock solution stability for 8 h. IPTG (Isopropyl ß-D-1-thiogalactopyranoside), is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon and it is therefore used to induce protein expression where the gene is under the control of the lac operator. 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.

To either of the below solutions add 3 ml/L IPTG stock solution. When pouring plates add 15 gm bacto-agar per liter. Solution 1:10 x M9 Salts Solution: 60 g Na2HPO4 30 g KH2PO4 5 g NaCl 10 g NH4Cl IPTG is an effective inducer of protein expression in the concentration range of 100 μM to 3.0 mM. Typically, a sterile, filtered 1 M solution of IPTG is added 1:1000 to an exponentially growing bacterial culture, to give a final concentration of 1 mM. 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 Stock Solution Stability.

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.

· Add 200 g of IPTG to the solution.

Molecular Characterization and Gene Expression Profiling

Dissolve 238 mg IPTG (sigma I-6758) in 10 ml DW for (100mM stock) store in 1 ml aliquotes at -20°C Generally a 1mM solution is an effective amount to induce the pLac promoter region. 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. IPTG (1M) Dissolve 2.83 g IPTG in 8 mL dH 2 O. Bring to 10 mL with additional dH 2 O. Sterilize by passing through a 0.2 µm filter.
