Week 3

26-07-2010

  • Lemaître experiment: 400 ml cultures of GFP Asaia, Ecc15 and P.Entomophila
  • Lemaître experiment: separating male and female drosophila
  • Transformation of the Base Vector with -Kan-ori- insert into E.Coli DB3.1
  • PCR of LovTab as a positive control to check if the PCR works (with own and Henrike's dNTP's) --> Run gel
  • Test-digestion of some of the Mini-preps (Ori alone, Ori-Amp) --> Run gel
  • Recovered the wildtype Asaia worked!!
  • WT Asaia strains arrived. Culture started


27-07-2010

  • Ligation C3/A3 + Ori + resistance (Kan, Amp, Tet, Cm)
  • transformation of the ligation products into E.Coli DH5a
  • Plating of transformed cells with selection of the vector and the insert
  • Colony PCR of E.Coli DB3.1 containing BaseVector + Ori + Kan --> running gel (twice, the first time failed)
  • Preculture of (maybe!!) WT Asaia for competence protocol
  • Sorting of male/female flies
  • Culture of 400 ml of different species of bacteria.


28-07-2010

  • Analysis of plating of transformed cells
  • Gel for check the Colony PCR
  • 250 ml Gly medium
  • OD measurement of preculture for competent Asaia --> too high. Start a new one!!!
  • Competent Asaia and stocking @-80°C
  • Plating of transformed E.Coli for double check
  • preparation of the pellets for infection with 3 different species of bacteria + OD measurements
  • preparation of tubes with 15 female flies
  • begin of the survival experiment: infection of flies --> check of the flies after 2h


29-07-2010

  • Results from plating of transformed E.Coli for double check and miniprep from some of them
  • Digestion with different restriction enzymes to check if we get the right length
  • Counting of dead flies one day after the infection
  • Observation of fluorescence of infected flies under the microscope


30-07-2010

  • Running a gel of the digested products of miniprep (29.07) --> bad results
  • Miniprep for the last 17 samples of replating
  • Digestion of 5 samples with 3 restriction enzymes to check if we get the fragments we expect
  • Running a gel for the digestion products
  • Counting of dead flies two days after the infection
  • Observation of fluorescence of infected flies under the microscope
