Part:BBa_K3733045

RNA Thermometer(heat-repressible) test system

Use a constitutive promoter (BBa_J23110), RNA thermometer (BBa_K3733011), strong RBS (BBa_B0034), fluorescent protein neGFP (BBa_K3733012), and an artificial terminator (BBa_B1006). Will express high levels of fluorescent protein below 28 ℃.

Usage and Biology

This is a composite part constructed to verify the effectiveness of the heat-repressible RNA thermometer.

Functional Parameters

We transformed this composite part into E.coli DH5α. We cultured both experimental group and control group at both 37 ℃ and 28 ℃ for 12 hours and detected RFU / OD₆₀₀ by a microplate reader. As the result shown in Figure 1, RFU / OD₆₀₀ data of the media at 28 ℃ are higher than ones at 37 ℃, which could explain the RNA thermometer is valid.
