Design Notes

This part was cloned without the promoter to avoid the biobrick illegal site existing on the U6 promoter. You can refer Waterloo iGEM 2015 wiki to see the full sequence of the U6 promoter in order to clone it in upstream of this part. The characterization data using this part in our purposes suggests that our CRISPR cas9 system is working using this sgRNA by suppressing RFP expression which uis under lacI promoter. Our experiment was done in BL21 and the sgRNA was in pSB3K3 backbone containing part BBa-K1645999. We were able to detect drop in RFP levels using this SgRNA coupled by S.pyrogenes dCas9.
