BBa_K098995 Kun Xue

In order to characterize the thermoinducible promoter properly, we have used 3 sets of control cells (not shown in graph):

  • Positive control cells: Containing the BBa_I13522, acting as a baseline comparison by constitutively expressing GFP.
  • Negative control cells: These contain the thermoinducible promoter on its own ( BBa_K098995) with no GFP attached to it. These serve as cells without any fluorescence.
  • Cells shifted from 28 to 42 degrees. This characterises the transition stage.

The characterization of the thermoinducible promoter is as follows:

  • At 28 ºC, there is no fluorescence (GFP) output because its expression is repressed
  • At 42 ºC, we can observe an increase in fluorescence (GFP) output,as its expression is no longer repressed

Hence, we can conclude that an increase in temperature de-represses the expression of the thermoinducible system.

As part of Imperial iGEM 2009 [http://2009.igem.org/Team:Imperial_College_London| The E.ncapsulator] project, we characterised this part using the composite BBa_K200022.
