Flipping One Pancake
The plan is to construct a plasmid that contains the following. Recombination would be detected as procuction of Tet resistant colonies.
- Amp resistance gene as in pSB1A3
- Hin recombinase gene driven by lacP (inducible in JM109 by IPTG or lactose), cloned from PCR product by Davidson team
- RE (recombination enhancer), synthesized by Davidson team
- One Pancake test construct:
araBAD promoter, inducible with arabinose
RBS
hixL recombination site, synthesized by Missouri Western team
CDS for Tet resistance in reverse direction
hixR recombination site, synthesized by Missouri Western team
double forward terminator, BBa_B0015 Plate DNA-1, Spot 1I
Flipping Procedure (draft)
- Grow JM109 in minimal media to exponential (A600 = 0.5)
- Induce Hin recombinase with IPTG (how much, how long?)
- Allow recombination
To Do List
- Plasmid prep pSB1A3, digest with EcoRI + PstI, Pase, gel purify
- Anneal hixL, hixR, and HixC oligos, then ligate into vector, transform
- Start overnights from colonies for double forward terminator, pBAD, mRFP
