96.99% of the stock of The Interpublic Group of Companies is held by institutions. IPTG (Isopropyl-β-D-thiogalactopyranoside) 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 of cloned genes under the control of the lac operon is induced by IPTG. It is also a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria. Prepare 100mM IPTG solution in dH 2 O (or dilute from 1M IPTG Stock Solution). Agar Media (Recommended) 1. Cool autoclaved growth media agar to 50°C.

IPTG can be used in the culture medium to prevent GFP-LacI from binding (+ IPTG). Upon IPTG withdrawal (−IPTG), accumulation of the GFP-LacI protein on the lacO arrays occurs in a matter of hours. This system has been widely used to look at chromosomal domain dynamics (several megabases) with large amplified regions of lacO repeats or dynamics of smaller regions (~10 kb) using single 2015-01-01 Buy GC2102 - IPTG, 99.5%, dioxane free (367-93-1) online from Glentham Life Sciences, a manufacturer and supplier of fine chemicals.

IPTG: Weigh out 750mg IPTG and suspend in 9mL ddiH20. Vortex to get into solution. Pipette 3mL of this solution into each fermentation vessel. (The target final concentration of IPTG is approximately IPTG, a non-metabolizable galactose analog, is commonly used in cloning procedures that require induction of β-galactosidase activity. IPTG powder can be stored at Room Temperature. For optimal shelf-life, we recommend storage, with dessicant, at -20oC.
