A temperature promoter cotaining clts repressor

This is based on part(BBa_K608351).Composite promoter (BBa_K608351) include the mutant type CIλrepressor so that it can express above 37℃.Compared with the part(BBa_K608351),it is more sensitive at 37℃.According to the essay, we choose five important sites A44G, G92A, C188T, G378A, A629T, which may enhance more than tenth times expression at 37℃，compared with wild type(BBa_K608351).

As for the measurement of this part, we will choice eGFP and FCM to test the expression at 37℃.
