Constitutive promoter; 0.4 REU

Design Notes

We performed [http://2009.igem.org/Team:Heidelberg/Project_Synthetic_promoters RA-PCR] with oligos containing binding sites for some well known generally activating transcription factors (Sp1, Ap1, CREB, NF-Y) which we identified from literature search [1],[2],[3]. We also added NF-κB responsive oligos as NF-κB has non-specific activity and is therefore used by a variety of viral constitutive promoters, e.g. the HIV promoter [4]. We picked 24 colonies, two of which we dismissed after a test digest. We then cloned the construct into Part:BBa_K203112 by SpeI and HindIII to obtain a core promoter.
