Salicylic acid sensor

This reporter is used to characterize the promoter J61051. GFP is produced when we add salicylic acid.

Usage and Biology

The NYMU-Taipei igem team characterize this inducible as an inducible promoter with GFP response as reporter. The following data was obtained by microplate reader:

The inducible promoter was induced with different concentration(0, 1.50E-07, 6.10E-07, 2.40E-06, 9.80E-06, 3.90E-05, 1.60E-04, 6.20E-04, 1.00E-03) every 30 minutes. We started the induction when the OD600 was 0.6-0.7. The fluorescence response was measured with plate reader.

The inducible promoter was induced with different concentration(0, 1.50E-07, 6.10E-07, 2.40E-06, 9.80E-06, 3.90E-05, 1.60E-04, 6.20E-04, 1.00E-03) every 30 minutes. We started the induction when the OD600 was 0.6-0.7. The fluorescence response was measured with plate reader. The red line indicate the Hill equation(P = Pmax*[SA]^n/([SA]^n+Km^n) ) fit of our dose-response data with error bar showing the standard deviation and the R square value of this fit is 0.99531. "n" indicates the hill coefficient(unitless), "Pmax" indicates the maximal promoter activity, and "K" is the salicylic acid concentration while P equals 1/2*Pmax
