  • pEsa_MRV + EsaR had a lot of colonies; backbone controls had fewer colonies.
  • LasR_MRV + pLas has lots of colonies, but its backbones had many as well.

Colony PCR for pEsa.

  • F Primer - RM seqver mod receiver LuxR home
  • R Primer - RM seqver regulator R
  • 8 colonies were picked for LasR_MRV + pLas ligation
  • 4 colonies were picked for the backbones (4 for ligation and 4 for no ligation)

Prepare liquid cultures for LasR to digest verify tomorrow. (picked 6 colonies)

Pick more colonies from Dr. Haynes' pAub plate (picked 4 colonies)

Prepare pLux_MRV, LuxR, for ligation

  • Both: Incubate at 37°C for 15 minutes, then heat deactivate.
  • Heat deactivation for E + X is - 80°C for 5 minutes, 65°C for 20 minutes
