Design Notes

[http://2009.igem.org/Team:Heidelberg/Project_Synthetic_promoters RA-PCR] (Fig. 1) was conducted with Oligos containing a NF-κB binding site, plus a small number of "general activators" (NF-Y, Sp1, Ap1, CREB). 33 clones were picked, miniprepped and transfected. NF-κB was then induced by the addition of TNF-&alpha (2.5µM) for 10 hours, and left uninduced as a control. The plate was then scanned by TECAN, an automated fluorescence plate reader. TECAN is very imprecise on eukaryotic cells, and the arbitrary fluorescence we meausred is not proportional to REU or another precise measure of mammalian promoter activity, but it can serve as a rough indicator of promoter induction. The result (Fig. 2) shows that most clones appear not to be induced by NF-κB, whereas others are induced at varying levels of strength. We picked clone 31 for submission to the registry and detailled charscterization,.
