Lab work

A - Aerobic/Anaerobic regulation system

Objective : characterize BBa_K1155000, BBa_K1155004, BBa_K1155005, BBa_K1155006

1 - Tranduction of Km in MG1655Z1

Abdou, Anaïs, Damir, Nadia, XiaoJing

We observed lysis areas in the strain MG1655Z1 Δfnr::Km after transduction. We will continue the transduction protocol.

Picture: lysed cells comparison.

  • 0µl phage(control): the petri dish is cloudy, bacteria are not lysed.
  • 50µl phage: the petri dish is clear, bacteria are lysed by phages.

Objective : obtaining BBa_K1155007

1 - Extraction of BBa_K115007 from DH5αstrain

Abdou

Protocol : High-copy plamid extraction

We extracted plamid from colonies number 10, 14 and 15.

Nanodrop

  • BBa_K1155007 in clone 10 : 38ng/µl
  • BBa_K1155007 in clone 14 : 48.5ng/µl
  • BBa_K1155007 in clone 15 : 52 ng/µl

The extraction was good. We will sequence our plasmids.
