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 thermosensors 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 (BBa_K2541051), 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.

sfGFP Measurement Device
In addition, we combined our cold-induced RNA thermosensors (cspA mRNA) with the promoter J23104 as a composite part for uploading, which is more conducive to other users directly, users can also only use a cold-induced RNA thermosensor according to their own needs.
Part Name Part Number sfGFP_optimism measurement device BBa_K2541402 superfolder GFP measurement device BBa_K2541403 sfGFP(BbsI free) measurement device BBa_K2541404 Introduction
They are three measurement device for sfGFP_optimism (BBa_K2541400), superfolder GFP (BBa_I746916) and sfGFP(BbsI free)(BBa_K2541401) fluorescence intensity, which is composed of Anderson promoter (BBa_J23104), RBS (BBa_B0034), sfGFP and double terminator (BBa_B0010 and BBa_B0012).
