Preparations
Preparations were done at the end of the week before
- Transformation of pDK48 and pTrc99a in E. coli DH5a (0.5 µl plasmid-DNA + 50 µl competent cells)
- Glycerol-stock of Vibrio harveyi BB120, BB886, mm30, BB178, BB125
- picked pTrc99a and pDK48 cultures and inoculated in 3 ml LB overnight
- V. harveyi cultured on LB+-Agar plate
- MiniPrep of pTrc99a and pDK48 from DHha
Cloning of LuxP
- PCR of LuxP from V. harveyi colony
- Gel Purification of LuxP eluted in 30 µl H2O
- Digestion of LuxP with SalI and NotI of pDK48 and LuxP-Gel-Purification product: 2 µl NEB-Buffer 3 + 0.5 µl SalI/NotI + 10 µl DNA + 7 µl H2O
- Ligation with vector:insert ratio 1:3 and 1:1
Cloning of LuxS
- PCR of V. harveyi genome and PCR purification
- digestion of LuxS and pTrc99a with BamHI/NcoI
- Ligation with vector:insert ratio 1:3 and 1:1
