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

  • 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
