Transduction of w121 strain

Titration of the stock of phage from 12.7.7. : ~10⁹ phages/ml : OK

FtsZ^TS strain screening

We want to test these strains :

• 121.4
• 121.5
• 121.6
• 129
• 1.129
• DCR 14.1
• DCR 14.2
• DCR 14.3

I made glycerol stock of these strains, stored in the freezer. Test :

• Spread these strains on two plates (preheated before spreading) :
  • One at 30°C
  • One at 42°C

The results tomorrow.

Minipreps

We have 2 clones for each plasmid :

• E0422
• E0241
• E0840
• B0030
• J61047

Elution within 50µL H2O
DNA is within the Miniprep box in the -20°C fridge.

Digestion products

DAP solution contamination test

Results :

• 50µL of H₂0 (control) OK
• 50µL of aliquot DAP 50mM (in use) OK
• 50µL of DAP 1mM CONTAMINATED
• 50µL of DAP 0.2 mM OK
• 50µL of DAP 50mM OK

PCRs

PCR : Assembly PCR Lox71-Fts1-FTsZ1 + FtsZ2
