We planned out that we will transform E. coli with the civI/civR system found in Chromobacterium violaceum. We will design MoClo devices that include these systems. In the meantime, we are beginning to design primers that will make the civI/civR system into a MoClo system by adding the the fusion site in addition to the BBS and SpeI sites. Then, we will develop a PCR strategy.
Our advisor, Traci, emailed different labs and PIs that work with Chromobacterium violaceum. Dr. Jim Thoden from the Holden Lab at the University of Wisconsin sent us genomic DNA.
We designed forward and reverse primers for CviR/CviI systems and ordered those primers. We are currently waiting on acquiring the primers to begin PCR.
Today, we did Phusion PCR using the genomic DNA of Chomobacterium violaceum as the template for the CviI and CviR systems. We ran the PCR product on a gel and the CviI did not appear on the gel. The CviR system appeared and we gel extracted the parts.
The gel concentrations are as follows:
| Sample | ng/µL | 260/280 | 260/230 |
|---|---|---|---|
| CviR_CD - A | 1.6 | 1.29 | 0.01 |
| CviR_CD - B | 5.4 | 4.48 | -28.27 |
