Checking pressure response ability of Plac
|
We examined changing of GFP fluorescence strength with pressurizing.At the same time, we examined fluorescence strength by adding IPTG under 0.1MPa.As a way of observation, we adopted a fluorescence microscope, FACS and FLA.FACS and FLA is for quantitative analysis of fluorescence strength. FLA’s result is Fig2, Fig3, Fig4. |

Figure 2, 3, 4 ; These charts show change of Geo Mean under each pressures. Figure 2 is about Plac-GFP. We constructed Plac-GFP. E. coli strains is JM109. Between 0.1MPa and 30MPa, Geo Mean almost don’t change.But at 50MPa Geo Mean increase sharply. Figure 3 is about promoter less-GFP (∆p-GFP) as a negative control. Between 0.1MPa and 30MPa, Geo Mean almost don’t change. But, at 50MPa Geo Mean increase sharply. Figure 4, is about Ptet-GFP as a positive control.Increasing pressure, Geo Mean increases. |
