Abstract Thermosensor sfGFP

Composite Part

  • Abstract

    This year, we added a total of 7 composite parts, including heat-inducible RNA-based thermosensor measurement device, heat-repressible RNA-based thermosensor measurement device, cold-inducible RNA-based thermosensor measurement device, cold-repressible RNA-based thermosensor measurement device, sfGFP_optimism measurement device, superfolder GFP measurement device and sfGFP(BbsI free)measurement device.

  • Thermosensor measurement device

    Part Name Part Number
    Heat-inducible RNA-based thermosensor measurement device BBa_K2541405
    Heat-repressible RNA-based thermosensor measurement device BBa_K2541406
    Cold-repressible RNA-based thermosensor measurement device BBa_K2541407
    Cold-inducible RNA-based thermosensor measurement device BBa_K2541408

    The thermosensor sequence is constructed on the pSB1C3 vector by Golden Gate assembly. The measurement device is composed of Anderson promotor (BBa_J23104), thermosensor sequence, sfGFP_optimism (BBa_K2541400) and double terminator (BBa_B0010 and BBa_B0012). We select a constitutive Anderson promoter J23104 as an appropriate promoter by pre-experiment. The sfGFP_optimism has faster folding speed and higher fluorescence intensity. The double terminator can reduce leakage (Figure 1). We characterized RNA-based thermosensors in E.coli DH5a.
