Source

The device is composed of arabinose inducible promoter pBad, CDS plu1537 and reporter mCherry. As the mCherry is already in pSB1C3, we linearize the part with enzyme PstI as backbone. The other two genes are amplified by PCR separately from parts BBa_I0500 (pBad), BBa_K1668007 (CDS plu1537).

We got pBad from Part Registry and the CDS plu1537 is a part we have constructed ourselves.

Design Notes

PCR

We use primer pBad F / pBad R to amplify pBad and standard F / plu1537 R for CDS plu1537.

Seamless assembly

We used seamless assembly as our assembly method so restriction digestion and T4 ligation can be avoided. Detailed protocol and instruction for primer design can be seen in our Protocol. By this way prefix sequence, pBad, CDS plu0840 and front twenty bases of mCherry sequence can be ligated seamlessly.

pBad R (R, 5’-3’): GCTAGCCCAAAAAAACG

standard F (F, 5’-3’): CCGTTTTTTTGGGCTAGCAGAAAGAGGAGAAATACTAG

plu1537 R (R, 5’-3’): CGGACTGCAGCGGCCGCTACTAGTATTATTAGCTTACAATCATATATTC


Transformation and confirmation

After seamless assembly, standard plasmid pSB1C3 containing plu1537 gene was transformed into E.coli DH5α. When single colony appeared on the LB plate, we picked out 10 colonies, respectively, as our template for bacteria solution PCR. In order to avoid the appearance of false positive clones, we used VF/VR as the universal primers. The positive clone and its corresponding raw bacteria solution were stored and samples were sent to do DNA sequencing.
