To assess if induction of repL gene expression could increase the output signal of a gfp reporter plasmid, E. coli TOP10 cells were transformed with the gfp.repL reporter plasmid and the transformants were induced with a range of L …
WebHowever, the presence of methionine in the medium induced a dramatic decrease in the Gfp- associated fluorescence (Fig. 2B), close to the level of the auto-fluorescence that is … WebThe presence of GFP fluorescence of organisms was assessed with the use of flow cytometry. The E. coli GFPIs were then observed for the period of 5 days in in vitro experiments in the culture medium. A single IPTG (isopropyl β-D-1-thiogalactopyranoside) induction of GFP gene appeared to be adequate for an expression of GFP protein for 5 days.
