WebCTAB solution which also defined as the cetyl trimethyl ammonium bromide and used in the experiment to remove the E.coli cells and also destroyed the membrane of the E.coli cells in order to release β-galactosidase enzyme that needed for the experiment from its content. E. coli is the source of the beta-galactosidase enzyme in the experiment. Web9 mei 2012 · As anticipated, upon induction at 8–10 μM IPTG, the intracellular concentration of the inducer was higher than that in the medium, but reached similar values at 20 μM IPTG. At higher initial concentrations of IPTG, the medium values were always higher than those inside the biomass. trafika crnuce
