Applications of BBa_K1431812
After we constructed this part, we tranformed into BL21 & DH5α to test expression effeciency. In the meantime, we did a comparison between BBa_K1431812 and BBa_K1431832 whose promoter is BBa_J23106, a relative weak promoter.
LB agar plate growth comparison
We spread the plate for BL21 at 10:00am on 15th, Oct and DH5α at 11:00am on 15th, Oct. The plate contains 34ug/ml chloramphenicol. Following pictures were taken every several hours after placing the plates into a 37℃ incubator.
JA is J23100,JB is J23106.

Conclusion
From the above observations, we found that expression in BL21 was stronger than that in DH5α, and the strength of promoter BBa_J23100 was unexpectedly weaker than BBa_J23106 provided by the 2014 iGEM kit plate.
