w121 growth

w121 culture launched on 22/07/07 did not grow ON: I had forgot to add DAP to LB-Erythro growth medium.

at 12h30, the following culture was launched:

  • w121 in 2ml LB-Erythro-DAP

We were unable to perform growth kinetics analysis of w121 in different DAP-supplemented media (because the machine is occupied for the night

Transduction of DapA deletion in MG1655

  • The transduction seems to have worked: isolation of clones on LB and LB+DAP for verification.

Migration of digestion products

MiniPrep


Digestion reactions

Each of the digestion reactions that follow were performed as follows:

  • 20µL DNA solution (miniprep or PCR product)
  • 5µL Buffer 10x
  • 0.5µL BSA 100x
  • 2µL of each of the 2 enzymes indicated
  • H20 qsp 50µL

NEB3 buffer used for XbaI/PstI double digestion NEBEcoRI buffer used for both EcoRI/SpeI & EcoRI/PstI double digestion reactions
