A 20 bp target sequence and PAM to make guide operator 3

The [http://2016.igem.org/Team:BostonU BostonU 2016] iGEM team synthesized guide operator sequences composed of a 20 base pair target sequence and a PAM sequence. The target sequence was made using a random DNA generator and entered into the CRISPR Design Optimization tool for the human genome (hg19). It was chosen among approximately 1000 other randomly generated target sequences due to its high optimization score ( > 98%) and high expression in an initial screen containing iRFP (figure 1).

The target sequence is expressed by a guide RNA (gRNA) expression vector (BBa_K1875011) from the BostonU Gemini Library. The gRNA binds to dCas9-VPR that targets a paired gRNA operator reporter (BBa_K1875014) to activate a downstream gene of interest.
