pSMB_MEASURE: Promoter Measurement plasmid (mammalian)

Plasmid map of pSMB_MEASURE

pSMB_MEASURE (SMB is for Synthetic Mammalian Biology) should be used for promoter characterization in mammalian cells. pSMB_MEASURE contains a reference promoter, JeT (Part:BBa_K203112), which is flanked by BBb_2 (Tom Knight) sites and can therefore be replaced by the promoter to be measured. JeT is ideal as a reference promoter for a variety of reasons. First, it has an intermediate expression strength; second, it is regulated by a wide variety of transcription factors and low levels of change in fluorescence among different conditions. Third, we want to pay tribute to its creators as pioneers in synthetic promoter research.

We separated JeT's core promoter from its proximal promoter by a HindIII site; it can therefore be used for screening of synthetic proximal promoters or for modifiying the strength of a promoter by core promoter swapping (described in our [http://2009.igem.org/Team:Heidelberg/Project_Measurement#Different_core_promoters_result_in_different_expression_strength wiki] ). In addition, it contains a FRT site which will allow for stable integration into mammalian cells also containing a FRT site. Thus, it provides the possibility to characterize the promoter in a defined genome and in this way helps to avoid some of the challenges we identified for promoter characterization. For the same reason, it also contains a mammalian selection marker (hygromycine). For the generation of the plasmid, please see Parts Design. As a reporter gene, it contains GFP, which is followed by a SV40 mammalian terminator. We generated another plasmid pSMB_REFERENCE, which contains mcherry instead of GFP. It can be used for normalizations to transfection efficiency.
