September 28th


Agarose gel electrophoresis for weight verification of 1F/24A/14K : none of the extraction contain 14K


Ligation with Ozyme protocol of 1F/24A and 14K in tet backbones

Ligation overnight of 1F/24A/14K


liquid culture of : blue, 8C/14K, L2/1N, 18A, phasin, phasin-intein, 24A and 14K



3 plasmid extractions (kit MN): Curli/22B-Tet; L2/1N-Cm; 18A-Amp. Samples are stored at -20°C.


Measures of nucleic acids concentrations with nanodrop (on 1,5µl extractions):

  1. Genomic DNA PHL818: 13ng/µl
  2. ompR PCR XT gel: 17,2ng/µl
  3. pSB1C3 Cm PCR XT gel: 4,6ng/µl
  4. pSB1T3 Tet PCR XT gel: 9,7ng/µl
  5. plasmid DNA L2/1N: 110ng/µl
  6. plasmid DNA Curli/22B: 12,5ng/µl
  7. plasmid DNA 18A: 31,7ng/µl

Conclusion: Not enough DNA (except for L2/1N)


Liquid culture Curli M.Gene in LB-Amp (from petri plate of 8/09) during the day, for plasmid extraction (kit MN), then DNA extraction was stored at -20°C.


Cloning ompR in pSB1C3: Digestion on 22µl of each DNA with 1µl EcoRI and 1µl PstI (Fermentas), in 6µl 10X buffer O during 1h at 37°C (thermomixer), then 20mn at 80°C (thermoinactivation, dry bath)


Ligation with T4 DNA Ligase (Fermentas): 30µl ompR E+P; 30µl pSB1C3 E+P; 7µl ligation buffer 10X; 1µl ligase; 2µl sterile water; at 15°C (thermomixer, no shaking), overnight


Liquid culture Curli M.Gene in LB-Amp (from petri plate of 8/09) for collection: at 37°C overnight
